James R. Barlow 78e8bf9cbf Use at most 3 Tesseract threads 
Based on a user suggestion and
tesseract-ocr/tesseract#2611, I reviewed thread limits and found that
thread limit of 3 is still beneficial, but not 4.

James R. Barlow 17ac9d7a9a Embed ICC profile in .ps (fixing Ghostscript 9.28 compatibility) 
Previously we included the
   filename, which required Postscript to run with file access enabled. For
   security, Ghostscript 9.28 enables ``-dSAFER`` and as such, no longer
   permits access to any file by default. This fix is necessary for
   compatibility with Ghostscript 9.28.

We use ASCII85 for a slightly more compact representation.

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.
