Issue DM-6577: Convert jointcalTask unittest into a validation measure
Now that jointcal has some basic unittests that check whether the relative and absolute astrometry are less than some value, we should convert those tests into validation measures a la [validate_drp|https://github.com/lsst/validate_drp]. This would help us track whether we are actually improving things as we tweak the algorithm and the mappings that we fit.
