fix deprecated setuptool install method

[netzego]

had some trouble to install your nice package via pacman (archlinux). didn't had much time. but this pr works. consider it as starting point. you might only need to put all your metadata back in -- as i deleted some of it, for a poc/dirty working version. cheers and thx.

/usr/lib/python3.11/site-packages/setuptools/__init__.py:84: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated.
