James R. Barlow 8a9f174f63 Fix XMP validation issue with /CreationDate 
Related to previous validation issue. If the /CreationDate had no
timezone, Ghostscript also creates invalid metadata. Work around this.
Also fix up PDF date decoding, and transcode dates to standardize them.

James R. Barlow 2131ad4670 Fix --remove-background error on PDFs with colormapped images 
It's unclear how exactly a

such images, but someone made it happen, so now we make sure
the image is okay.

Closes #262
