FLX-3402: declared statistics do not parameterise the chosen family

Family: seam/conformance (the 3000 band)

SEAM-FIDELITY-SPEC §1 draws every column from a distribution family whose parameters come from the column's declared aggregate statistics. A parameter that is neither declared nor a documented function of a declaration -- the midpoint of a declared range, the equal weights of a declared support -- would have to be invented, and an invented parameter makes a dataset nobody can account for. Declare the range, support, marginal rate or histogram the family needs.
