  1. Use Exif.SubImage1.0x7038 field for Sony lossless compression crop 

    Recap: due to crop size roundup to multiples of tile size (512)
Sony lossless files exhibit black areas if not further cropped down
to actual pixel area, which is covered by the sensor.

Exif.SubImage1.0x7038 seems to reliably provide the true crop size,
whereas Exif.SubImage1.DefaultCropSize only crops to OOC jpeg size
losing some pixel area
