h_import_calstate ---- Import a calibration state from disk
h_import_calstate clears and then recreates the pipeline calibration state
based on the set of applycal calls given in the named file. The applycal
statements are interpreted in additive fashion; for identically specified
data selection targets, caltables specified in later statements will be added
to the state created by earlier calls.
