[Help wanted] Update requirements.txt for Python > 3.7

[Daraan]

The current requirements are quite restrictive and outdated for newer python versions. I think we should update the requirements file with some version checks to allow Python3.7+ and the latest supported 3.10 to install and work smoothly

• opencv_python & numpy are the most important.
• networkx breaks in Python 3.10; needs at least networkx 2.7 if I recall correctly.
• Shapely needs at last +1 minor version
• ...

Maybe you can share your installations from 3.8 - 3.10 and help on this draft to craft a working version for the newer python versions.
