Supporting <group> in astropy.io.votable

See original GitHub issue

The VOTable recommendation includes a <group> entity (see section 4.9 of IVOA VOTable). This grouping is used by several IVOA recommendation, for instance to specify that a set of columns containing coordinates are related to the same reference frame. As far as I could check, it is not possible to build a VOTable with grouped param’s or field_ref’s.

An additional problem is that writing out <GROUP>s at <RESOURCE> level is not supported. This turns out to be a simple bug for which I have developed a fix. Still working on the big can of worms of constructing acceptable test cases given that this only became possible in VOTable 1.2.

I hope this work will also lead to fixing the problem in the present issue; stay tuned.

(Note that reading <GROUP>s at <RESOURCE> level from a file became supported after #6262 was resolved in 2017.)

Yes, I think so. I was not sure that topic was the place to push for the implementation of group, specifically.
