  Disallow merged upsampling with lossless decomp
  
  Colorspace conversion is explicitly not supported with lossless JPEG
  images.  Merged upsampling implies YCbCr-to-RGB colorspace conversion,
  so allowing it with lossless decompression was an oversight.
  9f756bc67a84d4566bf74a0c2432aa55da404021 eliminated interaction issues
  between the lossless decompressor and the merged upsampler related to
  out-of-range 12-bit samples, but referring to #690, other interaction
  issues apparently still exist.  Such issues are likely, given the fact
  that the merged upsampler was never designed with lossless decompression
  in mind.
  
  This commit also extends the decompress fuzzer so that it catches the
  issue reported in #690.
  
  Fixes #690
  Redundantly fixes #670
