add good pixels from an image to a coadd and associated weight map
The images are assumed to be registered to the same wcs and parent origin, thus: coadd[i+coadd.x0, j+coadd.y0] += image[i+image.x0, j+image.y0] weightMap[i+weightMap.x0, j+weightMap.y0] += weight for all good image pixels that overlap a coadd pixel. Good pixels are those that are not NaN (thus they do include +/- inf).
