- Keyframe extraction
- Media info probing during library scans
- Audio normalization
- Image extraction

* Add support for ffprobe's only_first_vframe for HDR10+ detection
* Add BitStreamFilterOptionType for metadata removal check
* Map HDR10+ metadata to VideoRangeType.cs
Current implementation uses a hack that abuses the EL flag to avoid database schema changes. Should add proper field once EFCore migration is merged.
