Issue DM-5767: Create custom basic coaddition code
Create script to do the following: * Takes a list of DECam exposure numbers * for each CCD, loads the corresponding calexps * creates a naive pixel-by-pixel coadd of the underlying images * Possibly either ANDs or ORs the masks (though perhaps not necessary) * Either sums the expusure time info from the headers, or averages them, depending on whether the images were normalised to exposure times or not * write the corresponding images out as coadded fits
