setup.py CLI is deprecated #448
Description
Running python setup.py sdist bdist_wheel is deprecated, so I think we should refactor our build setup a bit.
@boxed Do you have any opinion on what we should change or use in the future?
I'm not very familiar with package builds/distribution, but could read up on the topic. Currently I would consider replacing setup.py+setup.cfg with a pyproject.toml and flit as a build tool.

********************************************************************************
Please avoid running ``setup.py`` directly.
Instead, use pypa/build, pypa/installer or other
standards-based tools.
By 2025-Oct-31, you need to update your project and remove deprecated calls
or your builds will no longer be supported.
See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for details.
