Odin binding generator script

[monodop]

I generalized my clay.h parser and wrote a generator for odin bindings. Ideally we could write different generators for different output bindings to reduce the amount of work needed to keep everything up to date. For odin, there's a pretty large number of weird exceptions and edge cases, so it might be worthwhile standardizing them.

This generator/parser might be more effort than it saves though, curious to hear thoughts about it.
