Chess Engine doesn't work out of the box

[coatlessali]

As of now, the Chess Engine will fail to run out of the box, since it relies on a Windows binary of stockfish, compiled with avx2 support. The build was dropped to x86_64 for compatibility reasons.

Workaround:

Compile a binary of stockfish in ULTRAKILL_Data/StreamingAssets/ChessEngine/src with make build-profile ARCH=x86-64, and rename it to stockfish-windows-x86-64.exe. Then replace the exe in ChessEngine with the renamed binary.

Potential automated fix:

It should be pretty easy to have the script back up the Windows executable and replace it with a native one, or even compile from source. This opens up the neat opportunity of being able to compile to the architecture specific level of x86_64. Alternatively, it should be easy enough to obtain MacOS/Linux binaries from the releases and just ship those.
