need to replace yapsy for python 3.13 and later

[hppritcha]

It looks like the MTT python client will need major updating for python 3.13 and later. The main issue found so far with yapsy owing to the fact that it is relying on the deprecated and removed imp module:

File "XXXXX/lib/python3.13/site-packages/yapsy/PluginManager.py", line 132, in
import importlib.abc.Loader as imp
ModuleNotFoundError: No module named 'importlib.abc.Loader'; 'importlib.abc' is not a package

Looks like yapsy support ended in 2018. Probably best to move to pluggy (https://pypi.org/project/pluggy/) as that is being actively used by the Python development community
