Plugins do not start when run on python 3.12

[olivier-van-wijngaarden]

Recently I upgrade my laptop to Ubuntu 24.4 . The default python version I have now is 3.12. Since the upgrade AvNav failed to start.
The root cause seemed to be in pluginhandler.py. This uses the python imp module. This module was already deprecated a few versions ago, but since 3.12 it have been removed. From the imp module it uses only load_sources().
I replaced it as decribred below (inspired from https://devcodef1.com/news/1027645/replacing-imp-load-source-in-python-3-12), which worked for me:

< import imp

import importlib
657c657,659
< rt = imp.load_source(name, moduleFile)

---

  spec = importlib.util.spec_from_file_location(name, moduleFile)
  module = importlib.util.module_from_spec(spec)
  spec.loader.exec_module(module)

659c661
< return rt

  return module

---

Thanks a lot for bringing this up.
We did not test on ubuntu 24.4 until now - but having a more future proof solution will be great.
