Avoid regex in fnmatch crate

[livingsilver94]

Rewrite the fnmatch crate to not use regex. It's fast (comparable to the wildmatch crate), tested and fuzzed. Should be usable already. Run cargo bench to compare it against wildmatch and regex.

Documentation is in code an in the crate-level README.md file. Launch cargo doc --open --no-deps --document-private-items for a decent layout.

@livingsilver94 Is this something you feel like working on with us in alpha2...?

I think this PR is quite ready but I want to ensure it didn't break moss at runtime. Can you think of a manual test plan?

Rebase it on main and run with it in prod on your own system for a week or two yourself first?

Just a rebase.
