Principal columns defined for DP0.1 deployment on IDF

Based on SST/CET input, a subset of DP0.1 columns are now declared "principal" and will be highlighted (and used for default queries) in the Portal and in other TAP 1.1-compliant TAP clients. Key common columns (ID, ra, and dec) are also now moved to the top of the list of columns.

Summary by table of how many columns are "principal":

• object: 34/137
• forced_photometry: 33/747
• position: 7/29
• reference: 8/236
• truth_match: 22/30
