The SMPG JPEG-LS encoder uses .jls as the file extension for images, so
maybe 'MJLS'?

I have a question though.  Does JPEG-LS have its own SOF marker?  If so,
shouldn't any JPEG/MJPEG decoder check this before determining if it can
decode the image?  Or does the 'MJPG' fourcc always imply baseline JPEG?
