chore: use pre-commit and ruff (#116)

* chore: use pre-commit with ruff

* chore: fix warning: Invalid # noqa directive

* fix: B023

Function definition does not bind loop variable `ex`.

* chore: add check-manifest pre-commit

* chore: remove flake8 and isort config from setup.cfg

* chore: remove black, flake8, ... from dependencies and tox

* chore: add flake8-comprehensions

* chore: remove pointless noqa

* chore: keep type annotation syntax compatible with python 3.8
