Add ability to output greyscale and 1-bit PIL images without conversion to RGB.
The upstream Python 2.7 version of reportlab converts 1-bit PIL images to RGB
instead of saving them in a lower BPP format. They have since added the following
fix to their Python 3.3 branch, but it has not been back-ported.
