[Bug] Error when importing pyGHDL packages

[pidgeon777]

I tried to run this code:

from pathlib import Path
from pyGHDL.dom.NonStandard import Design, Document

but the second import crashes:

(common) C:\Work\Scripts\Python\PyGHDL>python test.py        
Traceback (most recent call last):

    members['__slots__'] = self.__getSlots(baseClasses, members)
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise AttributeError(f"Base-class '{base.__name__}' has no '__slots__'.")
AttributeError: Base-class 'Generic' has no '__slots__'.

I will provide any additional information if needed.
