Update parser to support through slippi version 3.12.0

[NickCondron]

Adds support for 3.10, 3.11, 3.12, and fixes parsing issues with 3.9 (closing #4)

Tested working on local replay version 3.12.

PS: the regex bug in peppi-derive was terrible to track down lol

Potential todos:

• Pretty print Slippi UID
• Add tests

Thanks for the PR; looks great so far. I'm super busy so I may not get a chance to review for a while, but I haven't forgotten about this.

Thanks a bunch for the contribution, and sorry for taking so long to review it. I've left a few comments. Besides those, we should also add tests for the new fields, and for the netplay code fix. Let me know if you don't have time to finish things up, and I can take over (but I may not get around to it for a while, either...).

No problem. Thanks for writing Peppi. I'm using it for one of my projects https://github.com/NickCondron/slp-search (not yet finished), and the performance is amazing. I can write the tests, but might not get around to it until this weekend.

Do you have any feedback about working on peppi, by the way? Were there particular areas that were hard to understand, or would've benefited from more documentation?

Yes. I'm new to Rust, so most of my problems came from unfamiliarity with the language/tools. However there were a few things.

From a Peppi development perspective, I didn't have too many issues. I was kind of able to copy how other things were done before. I suppose something that explained how the slippi(version) attribute works would be useful.

From a Peppi user perspective:

• The State enum in action_state.rs is hard to understand/use. Basically that's because it's a big macro. Probably it could be broken down into a normal enum with a few sub-macros. Or maybe there's some other solution. Really the macros in general are hard to figure out how to use - psuedo_bitmask/psuedo_enum
• It would be nice to have short/colloquial names for characters/stages/colors so that every project doesn't have to implement this sort of thing for their interface. Something along the lines of this https://github.com/project-slippi/slippi-js/blob/master/src/melee/characters.json
• Some of the enums/psuedo_enums should probably derive PartialOrd/Ord. For example without Port deriving PartialOrd it's tedious to determine which of two players comes first in a Frame<2> struct

If I think of more things I will add them here. If you think some of these are good ideas. I can create an issue and work on them down the line.
