  1. Add keep_rgb option to prevent RGB -> YCbCr conversion during JPEG write 

    libjpeg automatically converts RGB to YCbCr by default.  Add a keep_rgb
option to disable libjpeg's automatic conversion of RGB images during
write.

  3. Clarify JPEG tests for default/invalid subsampling 

    -1 is the default; 3 is invalid and should behave the same as the default.

  1. Fail if chroma subsampling selected when writing RGB JPEG 

    The user presumably doesn't intend to subsample the green and blue
channels.
