Issue DM-4830: Add error handling to PsfFitter in meas::modelfit
The {{ShapeletPsfApprox}} Task uses a class called {{PsfFitter}} which is not a {{SimpleAlgorithm}} and does not support error handling. Add error handling to this class, and modify the Task definition in {{psf.py}} to call an {{errorHandler fail()}} function when the algorithm's {{optimizer.run()}} call fails. Also, add unit tests
