- Run in PATH `black` binary on configured projects
- Can set wether we expect changes or not per project
- Can set what python versions are supported for a project
- if `long_checkout` True project will not be ran on CI

Will add to CI after I finish unit tests to avoid silly bugs I'm sure I have 🤪

Tests:
- Manual Run - Will add unit tests if people think it will be useful
- Output:

- Don't use asyncio.run() ... go back to the past :P
- Refactor results into a named tuple of two dicts to avoid typing nightmare
- Fix some variable names
- Fix bug with rebase logic in git_checkout_or_rebase
