Increase speed of h5parmpredict
Created by: revoltek
h5parmpredict is a necessary step to cleanup the dataset before facet imaging. The code seems extremely slow, no cpu seems to be used most of the time and after several days it did only few % of a full dataset (DDEcal is much faster in calibrating for instance). According to @aroffringa the bottleneck can be the predict part which should be made as fast as the DDEcal predict.
