tandem repeat catalog + variation clusters v1.0.2

This version contains a minor update to the TRGT catalog, involving changes to the STRUC and MOTIF fields.

The latest versions of TRGT no longer rely on a STRUC field, so the updated catalog repurposes this field to annotate whether a locus is part of a variation cluster. Additionally, the MOTIF field now has consistent motif ordering when multiple motifs are specified.
