Adding new pre-commit config

[x1101]

Adds .pre-commit-config.yaml, but doesn't add pre-commit to requirements at this time.

This means it can be used, but is not currently installed/required by default.

Doing a rebase to pull in the work from #507 and #503

Thanks for this @x1101 Let's merge #511 and then I think we're ready. Do you want to do a follow on to add pre-commit to requirements and add a ci check? Or do you want to do that as part of this PR? I'm leaning more towards the latter but I'll leave it up to you.

I'd also agree that it should be a distinct PR for that, in the (near) future.
