  - Adding PlaySessionId for better tracking.
  - Improves audio track selection
  - Uses mediaInfo builder for loading media.
  - Adds support for loading next/previous episodes
  - Translation support
- Updates progress reporting to Jellyfin to be more accurate and reliable.
- Fixes an error message in the direct player.
