feat: implement data coordinator for JackeryHome integration
- Introduced a new `JackeryDataCoordinator` class to manage MQTT subscriptions and data retrieval for all sensor entities. - Updated the setup process to create and start the coordinator, allowing shared data handling among sensors. - Enhanced sensor lifecycle management by registering and unregistering sensors with the coordinator. - Improved logging for better visibility into the coordinator's operations and sensor updates.
