- This PR adds the checks that are defined in the Makefile as pre-commit hooks. - Hopefully, the checks are equivalent to those from the Makefile, but I can't guarantee it. - CI remains as it is. - As I pointed out on discord, I experienced some conflicts between flake8 and yapf, so it might be better to transition to some other combination (e.g. black).
