fix: support double quote string enum

[MarshallOfSound]

Fixes #97
Fixes #98

The comment in #98 was correct, the regex method here isn't great and is one of the few regex smells we have left in this module. This rewrites our string enum extractor as a token-parser state-machine thing. Hope the comments I left are helpful, I'll note that this method already had really solid tests that helped me catch edge cases and this PR adds even more.

+1 on adding the "

Also +1 on removing | here; doesn't look like we have any docs that use that notation

dismissing as I fundamentally changed the entire PR after the initial approval
