AttributeError: 'NoneType' object has no attribute 'FootprintLoad'

Attempting to run an example with KiCad 8 gives the following error:

This is caused by an incorrect path to the KiCad library on Windows. In _guess_footprint_library_path(), it is hardcoded to use the KiCad 7 library.

Changing it to 8 causes this to work, but is not a robust solution.
