Move to pyproject.toml instead of setup.py

[pstelzig]

Problem description

The previous de-facto standard to package Python projects using setuptools and a setup.py is now being replaced by pyproject.toml. See the official Python packaging guide.

Desired behavior

Move from setup.py to pyproject.toml to be future proof.

Problem with pyproject.toml

With the default installation of pip under Ubuntu 22.04, the local installation process pip3 install --user . fails. It installs a package called UNKOWN. This bug is already known and no other fix than installing a newer version of pip has been proposed.
