This commit introduces caching mechanisms for OpenHome playlist operations to reduce redundant SOAP calls and improve performance. Key changes include:
- Added track IDs caching in OpenHomeQueue to avoid repeated id_array() calls
- Implemented cache invalidation for all playlist modification operations
- Added caching for source XML and source index in OhProductClient
- Updated playlist length, ID retrieval, and track ID fetching to use cached data
- Ensured cache is invalidated on write operations to maintain consistency
The caching strategy uses time-based expiration (1 second for track IDs, 10 minutes for sources) and employs mutex locking for thread safety.
