Title: Improved removal of SHA-1 hash upon reading in oiiotool and for IBA

This is a continuation of the recent checkin related to this. When
reading in oiiotool, or when preparing destination IB's for IBA
functions, we had removed any actual "oiio:SHA-1" metadata. But this
patch also ensures that any hashes embedded in the "ImageDescription"
are also removed.
