OCSADV-27 Parse VoTable magnitude errors and test #time 20m
OCSADV-27 Support parsing IR bands #time 20m
OCSADV-27 Fields are not good unique identifiers of table entries, use UCDs instead

OCSADV-27 Added support to parse ProperMotion from votable #time 3h
OCSADV-27 Ignore a special case when ucac4 returns a magnitude without a defined band, with ucd phot.mag;em.opt #time 30m
