Use uv

Since Astro team released uv recently, should we try it with ada-python?

From #60, it seems that there are still some issues being resolved for uv pip to be a drop in replacement on CI systems (example). I think it might make sense to wait for some of that to settle down.

I have been using ruff in place of flake8 and black on other projects, however, and am very happy with it. I'll switch this one to use them.
