Implement DALI Gateway Cache with State Management and Reconciliation

- Added DaliGatewayCache class for managing DALI device states, including address states, presence, and group statuses.
- Implemented methods for configuring cache, enabling/disabling features, and setting status update callbacks.
- Introduced state encoding/decoding for persistence and added support for CSV parsing.
- Created mutation handling for runtime status updates, group masks, scene levels, and settings.
- Developed reconciliation logic to handle incoming frames and classify mutations.
- Added tests to validate cache functionality, persistence, and DALI protocol handling.
