James R. Barlow e613db6a82 Fix Ghostscript 10.6 JPEG corruption by repairing truncated images ...

Ghostscript 10.6 has a bug that truncates JPEG data by 1-15 bytes.
This adds detection and repair by comparing output images to input
images and restoring the original bytes when truncation is detected.

- Add warning when GS 10.6+ is used with PDF/A output
- Add _repair_gs106_jpeg_corruption() to fix damaged JPEGs after
  Ghostscript processing
- Add unit tests for the repair function
