### Problem description
I was unable to use the LZMA de-compressor even though 7zip was able to
identify them as LZMA compressed and decompress them without a problem.
Under the debugger the `lzma_code()` call was returning
`LZMA_MEMLIMIT_ERROR`.
### Implementation description
I found online that the error can be fixed using `lzma_memlimit_set()`
using a value obtained with `lzma_memusage()`. I tried to avoid having
to call `lzma_code()` twice but if the functions are called before the
first `lzma_code()`the values of memory obtained fall short and error
occurs again.
I suspect that there are better ways to deal with this other than the
code proposed in this PR, but I haven't been able to find any.

### Problem description
https://github.com/WerWolv/ImHex/issues/1895
### Implementation description
Added code that handles streamed zstd data. It is based around the
[official
documentation](http://facebook.github.io/zstd/zstd_manual.html) and the
[example](https://github.com/facebook/zstd/blob/dev/examples/simple_decompression.c)
provided at the main zstd repo.
The loop around the non-streamed version was also removed because I
don't think it was doing anything (no `continue`s, `sourceSize` was
always being set to 0).
### Additional things
To test, I generated streamed zstd data with this python script:
```py
import io; import pyzstd;
with open("data.zstd", "wb") as f:
pyzstd.compress_stream(io.BytesIO(b'ab' * 100), f)
```
And then I ran this pattern script:
```
import std.mem;
import hex.dec;
u8 data[while(!std::mem::eof())] @ 0x00;
std::mem::Section data_sec = std::mem::create_section("data_sec");
hex::dec::zstd_decompress(data, data_sec);
```
Inspecting the section shows the correct data:
