Better processing of GFA targets:

- Handles reading Gaia columns directly from the sweeps in addition to matching to Gaia files. 
- Defaults to *not* matching to Gaia files.
- Makes Gaia matching radius stricter to return only the best Gaia objects.
- Retains Gaia RA/Dec when matching, instead of RA/Dec from sweeps.
- Fixes a bug where potential Gaia matches in some HEALPixels weren't being read.
- Adds a default Gaia epoch to the GFA file header (the actual epoch still needs passed through from the sweeps).

Should fix:

@sbailey: It would be useful  if you review this PR to check it fixes

or if we still need something else for the GFAs. An example output file is at `/global/cscratch1/sd/adamyers/gfas-PR342.fits`
