Use Ruff for formatting?

[cbrnr]

Ruff has gained a Black-style formatting option, which means that formatting is a lot faster (just like linting). Do you want to switch from Black to Ruff? I've done this e.g. for SleepECG here: cbrnr/sleepecg#204

Yes, definitely! Though we'd like to wait until the 2024 style is stable (and maybe until the formatter leaves beta) to avoid multiple small changes regarding that.
