     pngdec: relax condition for setting monoblack pixel format

     Ignore color_type information for setting the monoblack pixel format,
     only rely on bit_depth.

     In particular: fix Test_1bpp_grayscale.png from issue #172.

     This may work fine for some broken encoder, and not for others.
