[AstroPy] Table join with fits tables (or something else)

[Erin Sheldon]

The fitsio package supports querying a FITS file without reading the
data into memory.

You could use this functionality to perform a "join" by writing some
wrapper functions.  I would be interested in this if you did, and
maybe we could work it into the main package if it is general enough
