More flexible/extendible method to locate pypi repository

[BjarneHerland]

My 'miniforge' installation on MacOs 11/Arm64 pypi has a slightly different path to its repository. Since this may differ between operation-systems, versions of pip and/or conda-clones, some flexible and dynamic way to find the path may be useful.

This patch is a starting-point using the glob-module combined with some iterating. Should be extended to work on as many OS/pip-version/conda-clone -combos as possible
