FLX-3401: no distribution family is available for this column

Family: seam/conformance (the 3000 band)

SEAM-FIDELITY-SPEC §1 pairs six column types with four distribution families, and the pairing is closed. A column whose logical type has no row in that table, or whose declaration asks for a family the row does not allow, cannot be generated: choosing a family outside the table would produce a dataset the fidelity check was never specified over.
