To review

• Please check that I have not left any parameters/arguments/return values without type hints.
• Here's the RTD build for this branch. Check the "API Documentation" section (only for the files affected by this MR and the previous one) to confirm that all types are linked to relevant pages from external documentations (e.g., Python, Numpy, SKLL). There's no W&B yet since it doesn't seem to work. I have a ticket open with them.
• Check for typos and/or weird issues in docstrings.
