- Video rotation (0/90/180/270) now stays fully in planar YUV420,
preserving 10-bit HDR (yuv420p10le via PyAV uint16 planes) and the
source colorspace; no more RGB round-trip.
- AVIF images now go through the ffmpeg CLI path like HEIC: pyvips drops
CICP colour metadata, turning HDR sources into washed-out SDR previews.
- Fix pyvips "out of order read" on JPEGs needing EXIF rotation by
reopening with random access only when autorot actually rotates.
