Initial standalone version

TODO:

• test coverage
• update platform + tests
• (invalid) mypy unreachable code errors in light.py
  - [ ] make group entities use cluster handlers? - this can't be done until the API in Zigpy is compatible.
• make config schemas dataclasses
• make all events dataclasses
• device availability dispatcher replacement (handle similarly to group entities / lights?) Is this even needed? For HA maybe just use emit from our device and have HA use that to to update the proxy it holds
• sweep for unused methods that remain from the conversion
• prune unused constants
• verify all entity defaults to account for things that were previously handled by HA core
• rename entity classes
• remove ZHA prefix from class names
• handle zigpy controller reset correctly - Find a way to not reload the integration when a radio reset is sufficient
• remove any remaining commented out blocks after the above items are complete
• outbound events (relay events for UI, ZHA events for devices etc.) and clean up disparity between async_send_signal and emit and centralize on emit
• don't use event base to manage group state and refreshes. Use direct entity access instead for efficiency?
• Reduce counter sensor overhead (maybe another reason to pull in coordinator entity)
• Clean up handle_cluster_handler_attribute_updated - make sure entities are only using the data they intend to
• Clean up all to_json() methods

Can't unify group entities to use cluster handlers until Zigpy is updated to make the API consistent:

The logging in Zigpy also appears to need to be tweaked:

DEBUG    zigpy.group:group.py:259 [0x0002] trying to create new group 3 cluster id
