feat: Expose PInvoke-able analyzers

[Hona]

I'm not huge on rust, so feel free to be brutal in code review, or decline this PR

This is a stab at allowing the DLLs to be invoked by other languages (e.g. C#)

I have a sample repo using this change (passing tests!)

Integration test that invokes & asserts something about the data out :)

Also, benchmarking programatically running the exe, versus the PInvoke, gave me a good performance improvement:
