The BytesOfJPEGData key crashes if use is attempted.
The OffsetToJPEGSOI remains the same if modification via a Kies Accessor is attempted.
Are these keys really not metadata, and should they be removed from PMT? Talk to Chris Lin and
Dan Graham about these. If changing them messges up the image, then they should probably be
removed, OR, is there some way we would want to make them read-only?
