💥 Removed get_name from Quiddity class and simplification of Quiddity::container class

• get_name moved to get_id (Quiddity class),
• get_name moved to get_nickname and get_qrox_from_name moved to get_qrox_from_nickname (python)
• pyqrox is removed, pyswitch create methode now returns a pyquiddity. pyquiddity also has id() and nickname() methods so the code using qrox logic can be left unchanged, with only the pyquiddity object used instead of the pyqrox
• pyswitch on-quiddity-created and on-quiddity-removed callbacks give quiddity id instead of quiddity name
