Kevin K 8988853fb8 imp(ArgMatcher): huge refactor and deduplication of code
Tons of code has been moved into functions, deduplicated, made much
easier to read, maintain, and understand. Comments still need to be
added, but that will happen shortly. Modules have also been moved around
to follow Rust conventions and best practices.

All functionality remains exactly the same
