Missing astrometry catalogs in packUtils.catCodes

[stevenstetzler]

I've identified that at least catalog code X is missing from the packUtils.catCodes dictionary. It maps to Gaia3E according to this and this. Additionally, it looks like the mapping for W: 'UCAC5' is wrong, it should be W: 'Gaia3' and Y: 'UCAC5'. A few more seem to be missing based on what's available on both those pages.

From what I can tell, the mapping should be

catCodes = { ' ': 'UNK',
             'a': 'USNOA1',
             'b': 'USNOSA1',
             'c': 'USNOA2',
             'd': 'USNOSA2',
             'e': 'UCAC1',

           }

@federicaspoto What do you think of this? Does this look right to you? I will open a PR to made a change to the code if it looks good.

@stevenstetzler yes, it looks good to me. Thanks for checking it!
