optimize: Exclude soft masks (SMasks) from optimization
...
Soft masks are only allowed to be of colorspace DeviceGray so we
shouldn't use pngquant on them. For now, avoid this exceptional
case by excluded soft masks from optimization.

optimize: fix PNGs that were reduced to 1-bit being inverted
...
At some point the color gets flipped, we have to flip it again,
for mono.
Incidentally this exposed an unused
optimization. Should change the
first past to scan all images and
record monochrome xrefs, then optimize
JPEG and PNG, possibly adding
mono images to the monochrome
queue. Finally, do JBIG2 optimization.

Helps make it more explicit. Did not do this to tests because use of paths
