.lrc support

I've added support for reading lyrics from .lrc files alongside audio files, with comprehensive logging to track the lyrics processing. The implementation:

1. Checks for .lrc files in the same folder as audio files:

• Looks for matching filename (e.g., song.mp3 -> song.lrc)
• Logs when .lrc files are found and successfully parsed
• Includes details like file size and number of lyrics lines
• Maintains existing support for embedded lyrics:

2. Processes standard lyrics tags

• Handles language-specific lyrics tags
• Preserves multi-language lyrics support
• Added detailed logging for all lyrics sources:

3. Tracks .lrc file discovery and parsing

• Reports embedded lyrics tag counts
• Shows language-specific lyrics processing
• Includes success/failure status and error details
• Logs statistics like line count and sync status

The next time you scan your music library with debug logging enabled, you'll see detailed information about lyrics processing from all sources, making it easier to track how lyrics are being handled.
