13x Performance for Export chatlog, update rust_g to 0.4.6-vorestation

[ShadowLarkens]

VOREStation/VOREStation#9246

Profiler indicates that over 5 calls, there was roughly a 13x improvement by simply switching from << file writes to rustg_write_file.

Note: rust_g is no longer optional for this codebase. It's increasingly important for maintaining performance, and by using the generated .dm file from rust_g's build process (which does not allow for optional rust_g) we can keep up to date much more easily.

rust_g 0.4.6-vorestation is just rust_g 0.4.6 with this diff: (I'll bug Lesh to update our VOREStation/rust-g repo after tgstation/rust-g#39 is in)
