CI: Add pre-commit CI

This adds lines to pre-commit for CI to run isort and black from a comment to a PR.

For reviewers

• The PR title is short, concise, and will make sense 1 year later.
• New functions are imported in corresponding __init__.py.
• New features, API changes, and deprecations are mentioned in the unreleased
  section in CHANGELOG.rst.
• Contributor(s) are listed correctly in __credits__ in orix/__init__.py and in
  .zenodo.json.

@pc494 Can you add access to orix from https://pre-commit.ci

[pc494]

pre-commit.ci autofix

[pc494]

at a guess this failure is due to the style changes between 2023 and 2024. @CSSFrancis could you run locally so this comes up green as I imagine we need this merged before we can autofix.

[CSSFrancis]

@pc494 Yep you are correct. The joys of running black :)

[CSSFrancis]

@pc494 This should be fixed now and we can auto fix now which is nice.

[pc494]

Good.

I am going to merge this on the condition that @CSSFrancis remembers to add himself to the Zenodo when we get to #460. This PR closes #463.
