Relax colorspace checks in CPDF_DIBSource::CreateDecoder().

Previously the log just made sure the colorspace and the image have
exact matches for the number of colorspace components. Now, for some
colorspace types, check the type and make sure the number of
components meets or exceeds what is required by the spec.

Also do some refactoring.
