Fix Version/s: None
Increase the loading and processing speed of validate_drp following suggestions by Paul Price
1. Don't read in footprints
Pass flags=lsst.afw.table.SOURCE_IO_NO_FOOTPRINTS to butler.get
2. Work on speed of calculation of RMS and other expensive quantities. Current suggestions:
d. Consider boolean indexing in afw's multiMatch.py
Note that while this ticket will involve work to reduce the memory footprint of the processing, it will not cover work to re-architect things to enable efficient processing beyond the memory on one node.
