Issue DM-3538: Translate more mask pixel bits from instcal data quality mask of DECam data 
The mask pixel bits are defined differently in DECam instcal data from different pipelines, see http://community.lsst.org/t/decam-data-quality-masks/133 for a summary. The current mapping in DecamInstcalMapper is for the community pipeline Pre-V3.5.0. More mask bits were defined in DESDM y1 products. This issue provides full mapping for DESDM y1 products so all questionable pixels are translated into the MaskedImage.
