Measuring asteroid rotation periods in adam-core

A tour of the new rotation-period subsystem in adam-core - the joint multi-band Fourier fit, the staged frequency search, and the measured single_period / period_family / insufficient_data verdict, calibrated against LCDB, DAMIT, and Rubin's first asteroid discoveries.
