Yeah so this adds libogg, libvorbis, and libopus to the Rust library on the client. This is intended for use by the client soon-ish to replace .NET ogg vorbis implementations and add opus support.
This turns out to be a huge pain thanks to https://github.com/rust-lang/rfcs/issues/2771 . To solve this I ended up compiling the projects as staticlib and creating a build.py script to invoke the linker. This sucks a *lot* and I have yet to write the linker invocations for Linux/Windows, but it's probably the best option we have.
