Fix crash on UNDO/REDO shortcut press when in "title screen"
### Problem description
ImHex crashes when (by default CTRL + Z/Y) undo/redo is pressed when on
"title"/"starting" screen (no file open, tested on Windows release build
and Linux [WSL] from-source build).
This is due to the shortcut's callback being called even if the
`provider` is `nullptr`. (see `createEditMenu` function).
Theoretically, this is prevented by the `enabledCallback` function
passsed to `addMenuItem`. In this case, though,
`addMenuItem` correctly propagates `enabledCallback` to menu item
creation but does not pass `enabledCallback` to
shortcut creation. Thus, when handling shortcuts, `enabledCallback` is
not used at all and the shortcut's callback
can be called in contradiction with its preconditions. (specified by
`enabledCallback`)
### Implementation description
The implementation wraps the callback in a check that decides whether
the shortcut is enabled or not.
(see changed files)
```c++
auto callbackIfEnabled = [enabledCallback, function]{ if (enabledCallback()) { function(); } };
```
This function is then passed along instead of the `function` (shortcut's
callback).
Alternatively, we can check for `nullptr` in the callback directly. This
would require modification of `createEditMenu`'s contents.
(I did not choose this implementation because I do not think it
addresses the root of the issue).
### Screenshots
None
### Additional things
I'm not sure how big of a deal it is but I am unsure whether I can
capture (`[enabledCallback, function]`) by reference or not.
### Problem description
As described in #1846:
- the `Edit the Hex` achievement doesn't unlock when it should
- the `ROM Hacks` achievement is not using event-driven architecture
(the functions call `unlockAchievement` themselves)
### Implementation description
Firstly, for the `Edit the Hex` achievement:
- replaced the old event listener on `EventPatchCreated` with a listener
on `EventProviderDataModified`, which picks up bytes changes
- ensured the provider data change comes from a File provider, else
unlocking the achievement wouldn't make sense
- *Note*: a discovered side effect is that the "Fill" function modifies
the provider byte per byte (with a for loop)
- there is no use in testing the size of the data change, as it is
always 1 byte
- the Fill function could probably be reworked to fill in whole regions
at a time?
About the `ROM Hacks` achievement:
- implemented the new, still unused `EventPatchCreated` event.
- signal signature is `const unsigned char *, u64, const IPSKind`:
buffer pointer, buffer size, and IPS kind (IPS/IPS32)
- make use of the `::post` and `::subscribe` methods on said event to
unlock the achievement
- **WARNING::behaviour change**: the event's `post` signal has been
moved in the success branch of the IPS generation condition, meaning
that achievement will only unlock if IPS patch export has worked. I felt
it would make more sense than unlocking an achievement on an error, if
there was any to raise.

Fix the AES ECB mode in the data processor along with some other misc
fixes:
- Fixed nullpointer node not working
- Fixed crypto module incorrectly using mbedtls api
- Fixed crypto module ignoring mbedtls errors
- Fixed silently ignoring of errors in AES node
Even tough the sound visualizer has `channels` as one of its parameters
it wasn't using it properly.
### Problem description
The biggest problem is that at each frame the index was being advanced
per channel frame_count increments. The number of channels also
determines how many graph will be needed to display the graphs of the
visualized sound files. Besides these two problems there were many
others like incorrect playback time, cracking audio, etc. which will not
be mentioned.
### Implementation description
To sample the signal a channel sampler was created based on the one used
previously that returns as many sampled signals as there are channels.
This PR aims hopefully at fixing all the problems encountered, and it
has been tested extensively using `Audacity` exported samples to ensure
the visualizer fidelity on playback and graph appearance.
### Screenshots
### Problem description
This PR aims at making inline visualizers work on the data inspector so
that more rgb encodings can be added as custom pattern language
inspector rows. This was never setup to work because the inline
visualizer rendering function was a private member function.
### Implementation description
In order to be accessible from the inspector class the rendering
function was made public.
### Additional things
Missing still is the tooltip to make it behave like other color entries.
### Problem description
Loading a file on the command line or using the context menu in windows
was triggering an achievement before the achievements file was loaded.
This resulted on the achievements.json file to be overwritten with all
the achievements reset except for the one to open files.
### Implementation description
This PR fixes the problem by introducing a boolean that is used to check
if the file has been loaded.
