Checklist

Before a pull request can be merged, the following items must be checked:

• Make sure your code is properly formatted. isort and black are used for this purpose. The simplest way is to use pre-commit. See instructions here.
• Doc strings have been added in the Google docstring format on your code.
• Type annotations are highly encouraged. Run mypy to type check your code.
• Tests have been added for any new functionality or bug fixes.
• All linting and tests pass.

Note that the CI system will run all the above checks. But it will be much more efficient if you already fix most errors prior to submitting the PR.
