MAINT: Update testing (use Black, Ruff, precommit hook)

[scott-huberty]

Time to tighten up the screws. Let's see what breaks.

• Reconfigure style job to make sure we are testing our whole codebase.
• Tests should fail on warnings so that we can catch and resolve them before they become errors.
• Use black to autoformat code (88 characters allowed, yay!)
• Swap out Flake8 for Ruff (built on Rust so a bit faster, allows 88 chars, and integrated with black)
• add a precommit hook (catch style issues before pushing to open PR's).
• Big picture: This should relieve us from having to manually manage all those pesky flake errors.
