Ruff handles black, flake8 and isort in one package, and is way faster. The isort rules had not been enforced, so this commit includes a lot of import resorting changes. I switched to flake8-bugbear and the standard black-compatible line length of 80 + 10% (so max 88 characters), so some line reflowing is included too. Finally, because bugbear rightly points out that `setattr()` is less performant, I've switched the `__signature__` assigment back to using a direct assignment with type ignore comment.
