[IPP] Duplicate media sizes in registry...

All,

Zdenek Dohnal (Red Hat) and Benjamin Gordon (Google) have been updating CUPS to support newer registered media size names from the IANA IPP registry.  During the review process we discovered that several duplicate sizes have been registered:

  iso_id-3_88x125mm vs. iso_b7_88x125mm (registered by Canon in 2018)
  om_postfix_114x229mm vs. iso_c6c5_114x229mm (both defined in 5101.1!)
  prc_3_125x176mm vs. iso_b6_125x176mm (both defined in 5101.1!)
  prc_5_110x220mm vs. iso_dl_110x220mm (both defined in 5101.1!)
  prc_10_324x458mm vs. iso_c3_324x458mm (both defined in 5101.1!)

I propose that I remove the first form from the registry in favor of the second to favor ISO paper sizes over national/special purpose sizes.

Thoughts?
