ZSTD precompressor (Side project)

[Razor12911]

Hi guys, here's another tool and to be honest, I have no idea if this thing works properly, I don't have space on my PC and I don't want to start deleting stuff without proper inspection as to what is important and what isn't.

As you can see XD: Capture74.PNG

Anyways enough about that, I did run a single test on the first 200mb of Resident Evil 2 of that massive pak file it has and this was the result:

Compressed 1 file, 209,715,200 => 390,911,469 bytes. Ratio 186.40%
Compression time: cpu 0.38 sec/real 10.11 sec = 4%. Speed 20.73 mB/s

Extracted 1 file, 390,911,469 => 209,715,200 bytes. Ratio 186.40%
Extraction time: cpu 0.63 sec/real 8.06 sec = 8%. Speed 26.03 mB/s

The final result is for you to find out.

As long as they have the necessary zstd headers for some zstd api functions to work because this is based completely on zstd functions, I didn't come up with custom functions like I did with oodle or workarounds or anything like that.

All should have the 0xfd2fb528 header, as a result. This shouldn't work on Mass Effect Andromeda because if I'm not mistake, that one has a header 0xfd2fb526 and I think different functions existed for that version.
