e75b6280fd Try reading compressed data directly to see if Leptonica will add predictor 
Turns out it does not transcode at all in this case, so probably going
to revert to transcoding PNG -> PNG. However if pngquant or similar is
done, this API will still be useful.

b069de0caa Use Leptonica to rewrite all PNGs with predictor 
Leptonica does a better job of encoding them than Ghostscript, about -15%.
For a test file 450k worth of
PNGs was reduced to 388k with no loss of quality.

d8ac6e28ab Convert monochrome images to JBIG2 
Awkwardly using fitz and pikepdf, transcode monochrome to CCITT.
This requires _OCRMYPDF_NO_FITZ=1.

00000x.opt.pdf can be checked for JBIG2 to confirm, but this file is
not passed to the output since it's not all wired up yet.

a95ffcdc46 Experimental add jbig2 
It appears that fitz forces conversion of jbig2 to ccitt no matter what,
so pikepdf will be needed to patch jbig2 images.
