Ruff linter

[CompRhys]

Addresses #534. Much faster linting and formatting using 1 tool as opposed to 3.

Hey @CompRhys, looking at your changes, some of them will break compatibility with Python version 3.7 and 3.8.

[CompRhys]

I ran with target-version = "py37" and so I would assume that nothing would be broken. If you want to keep backwards compatibility to 3.7 would you take a PR adding a CI matrix as I shouldn't be installing an end-of-life python version without security fixes on work laptop?

I think these kind of type hints: str | Path | None are not supported with older python versions. Why do you want to change the way we do type hints?

I think these kind of type hints: str | Path | None are not supported with older python versions.

they are actually, if you add from __future__ import annotations to the start of a module (inserting that import can be automated with ruff). it backports the leaner type annotations to 3.7

Good to know. Is there any guidelines from Python to prefere these kind of annotations?

[CompRhys]

The pep for it was https://peps.python.org/pep-0604/ generally I think the preference has been to move towards not needing to explicitly import anything in order to type hint standard types such as list, str or combinations thereof.

yes, from __future__ import annotations is only necessary below 3.10. above, the new syntaxes works without side-effect imports which is part of python's move to enable more type safety
