Lint and format code with Ruff

This replaces Flake8

In previous configuration:
 - "B" errors were supposed to be caught but
flake8-bugbear was not installed so it couldn't work.
 - "B9" seemed to be unrequired because already taken into account with "B"
 - "T4" corresponds to flake8-mypy but it was not installed.
