* Added github actions for PRs
* Added some rustfmt::skip attributes
* Applied formatting
* Added rustfmt component in action
* Configured to use rustfmt version 2 which fixes some comment formatting
* Removed ready_for_review condition for github actions
Since it has the synchronize condition, it will update after each
commit, whether in draft or not, so I think this should be alright
I wanted to make this a bit more modular, so it's easier in theory to
write external crates that can reuse bits, and selectively compile in
bits, such as adding new systems or new cpu implementations
