Issue DM-3033: Add Sdss3Mapper to ingest, convert and map SDSS-III "frame" files
SDSS-III does not use the fpC file format for science images. Science images are now released as ["frame" files. | http://data.sdss3.org/datamodel/files/BOSS_PHOTOOBJ/frames/RERUN/RUN/CAMCOL/frame.html] The primary science image (hdu0) comes background subtracted and calibrated to units of nanomaggies, with the backgrounds and flat-field conversions included as extensions. The astrometric information is in hdu3 instead of a separate asTrans file. obs_sdss should be able to ingest frame files and map them to load as dataset "raw." It should also optionally replace the backgrounds and de-calibrate to convert the units back from nanomaggies to counts. This will be implemented as lsst.obs.sdss.sdssMapper.Sdss3Mapper.
