* Add register_packet_callback() and self._packet_callbacks

* Add notify_packet_callbacks()

* Add generic packet reception API

- Add register_packet_callback() method for registering packet callbacks
- Add notify_packet_callbacks() to dispatch packets to registered callbacks
- Support both global callbacks (filter=None) and address-specific filtering
- Add _packet_callbacks storage using defaultdict for callback management

* Add generic packet reception API

This implements a generic packet reception API as referenced in issue #1468.
It allows for registration of callbacks for raw ZigbeePacket objects, and enables
future features like TouchLink support via inter-PAN communication.

- Add register_packet_callback() method for raw packet callbacks
- Add notify_packet_callbacks() to dispatch packets to callbacks
- Add _packet_callbacks storage using defaultdict
