TIFF_PHOTOMETRIC_YCBCR seems to simply be a flag to signal yuv data. If it's set, 
init_image() chooses the pix_fmt by looking at some other values in the file.
I copied the exact same check used in other compression algorithms (lzw, packbits, 
even raw) to know if it's yuv or rgb, and process it if the former. So if there 
hasn't been any kind of mismatch in those, it shouldn't in this one either.
