[Python] Yolo example + VS feature Inheritance

[SamFlt]

This PR introduces:

• A display factory on the Python side
• A visual servoing example using YoloV8 from the ultralytics package
  *Generator
  • Parsing of inner classes
  • Exposing protected members. This will be helpful for Python class inheriting from a C++ ViSP class
  • Pointing to a trampoline class in the generation code.
• A custom trampoline for vpBasicFeature allowing to inherit this class from Python. The python class objects can then be forwarded to the C++ side. This should probably done for other relevant classes.
