LibGfx: Decode paletted and grayscale images with 1/2/4 bit depth
When dealing with png data that has less than 8 bits per pixel, round
up to the next byte when allocating per row buffers and streamers. This
fixes decoding odd sized PNGs with less than 8 bits per pixel.
Also added a test page with some odd sized palleted PNGs.
