James R. Barlow 2a52c6dec2 optimize: skip images with unusually small dimensions 
They're unlikely to be handled well by our recompressors. It seems
that JBIG2 cannot handle very small widths.

Fixes #732

James R. Barlow c6caff90a1 optimize: only re-insert pngs after pngquant 
Previously we attempted to reinsert all PNGs, but it appears to be
unlikely that Leptonica's API is actually capable of optimizing the PNG
before it inserts it.

In any event qpdf has gained image optimization capabilities as well
which we coudld borrow.

James R. Barlow b2cfaedf91 optimize: Don't reinsert 1bpp images 
There seems to be version to version inconsistencies between
Leptonica's photometric interpretation of 1bpp images, in
particular commit a0692307 introduces a change to force transcoding
in this situation.

However, I never entirely got to the bottom of where the problem
is, and in any event 1bpp images are probably better optimized
by JBIG2 than pngquant, so we're going to stop running them through
pngquant.

James R. Barlow 4f69ace868 optimize: fix all JBIG2 images binned on last page 
During some past refactor it appears we now end up treating
all JBIG2 images as if they appeared on the last page in the
file. This bug had no visual side ffects but probably led to
suboptimal JBIG2 encoding.

James R. Barlow b27b92fbf3 optimize: on aggressive settings try JPG to PNG transcoding 
If the color count of an image is low such as when black and white
documents are scanned in color, PNG with lossy quantization may
produce a superior encoding to JPEG. This is expensive to test however.
