Testing various fonts and sizes I realized there were still problems
with the layout of the bit labels. Also I reorganized the code so that
lambdas are defined just before they are used. Comments needed
punctuation too.
Part of the problem was that I had been assuming all along that the
check boxes were ImGui's originals which are always square. In actuality
the width is determined by the width of the character for '0'. Also
ImGui table was adding spacing to separate cells which made the boxes
not start at same place as column. Also for some reason using indent of
zero didn't work as expected but using 0.1 pixels worked. With those
problems fixed it is fairly easy to make sure the labels are centered at
the box except when the first mantissa checkbox gets a label which is
wider that the box width. Before and after show results for different
fonts.

### Implementation description
I synchronized the json key order with `en_US.json` in each lang file.
### Additional things
Here are simple python script that make this change
```python
import json
from collections import OrderedDict
original = "./en_US.json"
modified = [
"./de_DE.json",
"./es_ES.json",
"./it_IT.json",
"./ja_JP.json",
"./ko_KR.json",
"./pt_BR.json",
"./zh_CN.json",
"./zh_TW.json",
]
for modify in modified:
dict_2 = {}
with open(original, 'r', encoding='utf-8') as f1, open(modify, 'r', encoding='utf-8') as f2:
dict_1 = json.load(f1)
dict_2 = json.load(f2)
dict_1_translations = dict_1["translations"]
dict_2_translations = dict_2["translations"]
ordered_dict_2 = OrderedDict((k, dict_2_translations[k]) for k in dict_1_translations.keys())
dict_2["translations"] = ordered_dict_2
with open(modify, 'w', encoding='utf-8') as f2:
json.dump(dict_2, f2, ensure_ascii=False, indent=4)
```

Updated Traditional Chinese (Taiwan) translations for ImHex.

### Problem description
The issue seems to only affect the web version of ImHex but it is not
clear why. The labels of the checkboxes that represent bits in the IEEE
745 floating point tool were lay out incorrectly.
### Implementation description
The new code ensures that the bit labels are centered and located in the
middle of the checkbox regardless of the font size and the dear imgui
sized checkboxes.

This will simplify the codebase in the pattern drawer. It returns early
on conditional statements and reduces the amount of nested code making
it easier to read and track while developing.
I noticed the bad score on code factor so I reorganized it to make it
more readable and maintainable. In order to break down the big function
into it much smaller parts I encapsulated all the variables that the
functions need to access in two classes, one for the imgui related
statics and the other for non-static variables.
When writing the smaller functions I was noticed that there was room to
simplify the existing algorithms by writing functions that could be
called by parts that previously shared no code. I tested the changes the
same way I tested the original and it seems to work the same way but
maybe a bit faster. Although it may be possible to further optimize the
present code code factor no longer flags the function at all.
As discussed (many times) on Discord, does the same as the new favorite
tag, but instead allows you to add multiple groups.
Initially, this would cause some insane issues with draw/reset
(apparantly) fighting eachother in the pattern drawer. After a lot of
trial and error, I decided to rewrite the flow that is responsible for
calling reset. Now evaluating patterns is the one to decide when the
reset happens, not the core "game"-loop.
To make sure that draw and reset can never happen at the same time, the
mutex originally used for the favorites has been repurposed. Due to the
restructuring, the mutex in the favorite-task is no longer needed, as
that will only ever kick-off after reset is called and if there are
actually patterns, which can never line up to be accessed on different
threads at the same time.
Last but not least, I noticed that hard crashes could result in your
config file getting overridden. I added a check to prevent that.
Last I issue I can see is that if you use an excessive amount of
favorites/groups, a crash can still happen, but it only happens when you
close the program (occasionally, but unpredictable). Before, this would
happen if you ran the evaluation a second time. I boiled the cause of
the crash down to these lines of code in evaluator.cpp >
patternDestroyed:
```cpp
if (pattern->isPatternLocal()) {
if (auto it = this->m_patternLocalStorage.find(pattern->getHeapAddress()); it != this->m_patternLocalStorage.end()) {
auto &[key, data] = *it;
data.referenceCount--;
if (data.referenceCount == 0)
this->m_patternLocalStorage.erase(it);
} else if (!this->m_evaluated) {
err::E0001.throwError(fmt::format("Double free of variable named '{}'.", pattern->getVariableName()));
}
}
```
Specifically, trying to access the `*it` is the reason for the crash
(this was also the cause of the crashes before my fixes, but then during
evaluation).
I'm suspecting the root cause is somewhere in the `.clone` methods of
the patterns. I'd say that for now a crash when closing the program is
more acceptable than during evaluation (which can even happen if you use
favorites).
From #1265, Looks like Error Popup doesn't handle properly in some
circumstances.

### Problem description
Ref #1210
### Implementation description
Call
[`SetFileTime()`](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfiletime)
everytime `FileProvider::save()` is called.
### Additional things
I moved the call to `File::close()` from `FileProvider::open()` to
`FileProvider::close()` because `SetFileTime()` requires a file handler
as input, so I need `File::m_file` to be valid.

see #723
### Implementation description
<!-- Explain what you did to correct the problem -->
`xdg-desktop-portal-wlr` is not relevant because it does not provide the
FileChooser interface.
`xdg-desktop-portal` needs the `WAYLAND_DISPLAY` env var on wayland and
the `DISPLAY` and `XAUTHORITY` env vars on xorg. If the dbus user
session bus is not run in a way that it already gets those variables,
they must be given via `dbus-update-activation-environment(1)`.

### Problem description
Currently, the providers use the method `isSavable()` to determine both
if they can use "Save" or "Save as".
This behaviour is problematic because some providers may need to be
saveable but not saveable as: for example the view provider. The
original provider may not allow to be saved.
### Implementation description
I separate these two behaviour by creating another function:
`isDumpable()`, that return true by default but can be overridden by the
provider to return false, if the provider should not be dumped in any
way.
### Additional things
While I was at it, I also marked "export" operations as needing the
"dumpable" flag. That way, we can't accidentally export the whole
address space of a process as base64.
I also added documentation for these some functions in Provider
This PR fixes some things about crash handling:
- when the terminate handler is called, immediately set it back to the
original one, so can't make a recursion if the crash-handling code fails
- Only save projects if the crash occured after Imhex finished startup
- do not update the project location when saving the crash backup file:
this will remove problems when `EventAbnormalTermination` is called
before `crashCallback()`
I also added a bit more documentation
In order to do this I add to make some other additions :
- Add a warning popup (TODO, maybe add some icons to differentiate
error/warning popups in a future PR ?)
- create showError() and showWarning() functions, as helpers to show a
message both to the logs and as a popup
