Issue DM-6824: Use meas.algorithms.astrometrySourceSelector in measOptimisticB
Now that there is a working astrometrySourceSelector (just merged in meas_algorithms from DM-5933), we should get matchOptimisticB working with it. This would entail replacing matchOptimisticB.SourceInfo with AstrometrySourceSelectorTask and tweaking the latter to do whatever matchOptimisticB needs, and removing SourceInfo.
