Chore/cleanup

[wietzesuijker]

Cleanup changes split from another PR:

• This changes the default from python 3.8 to python 3.10 for the dev env (following what is used in the .github/workflows).
• Changes spelling defaults from words like finalize to finalise (sorry for the UK push, happy to go the other way, just want consistency)
• add some docstrings to functions
• use built in types for dict, list and tuple rather than from typing import Dict, List, Tuple. This is not implemented library-wide here, as I was only touching some files for the other PR. Arguably using Optional can also be dropped, as var[list[str]] = None is valid python.
