pyshader appears to be retired and failing

So pyshader github repo seems to be retired, and the examples are failing for me with

This seems like a bug in pyshader, but it isn't getting updates then it probably should be moved on from.

I would be keen to find an alternative to pyshader but seems there's no similar libraries to achieve this - currently CI examples are passing, perhaps this is a python compatibility issue
