missing pyproject.toml

[ymahlich]

When installing a python package locally via pip that I actively develop on I prefer doing so via pip install -e/--editable <path-to-local-git-repo>. This allows me to being able to import the package from anywhere without having to reinstall it after every change.

setuptools / setup.py is being deprecated. pip recommends switching to a pyproject.toml.

I don't think this is necessarily urgent, but maybe something to keep in the back of our heads.
