7861578bd6 for ReadXXXX() image-readers, use the value of pic->use_argb
This is to infer the needed conversion to YUV(A) or RGB(A).

This is useful to avoid some conversion steps between ARGB and YUVA.
For instance, if the input file is a JPEG, we decode to RGB and
convert to YUV right away, without the intermediate step to ARGB.

The only caveat is that cropping/scaling might give slightly different result,
because of YUV420 downsampling. Therefore, we omit this feature
at cwebp level, when -crop or -rescale is used.
