Rust-based atmospherics for Space Station 13 using auxtools.

The compiled binary on Citadel is compiled for Citadel's CPU, which therefore means that it uses AVX2 fused-multiply-accumulate. Yes, really. If you have issues, compile it yourself, via cargo rustc --target=i686-pc-windows-msvc --release --features "all_reaction_hooks katmos" -- -C target-cpu=native. It has to be 32-bit, mind.
