optimize: ccitt header fixes
...
Changed to match TIFF spec's use of unsigned types, eliminated check for
/Columns.
There is some complex behavior for /Width != /Columns and
(/Width, /Columns) mod 8 != 0
that is not described well in the PDF spec.

Iterate images with pikepdf / fix mono PNG corruption
...
To work around PNG corruption problem in PyMuPDF for monochrome images,
extract and save monochrome CCITT with synthetic TIFF header.
Works better but currently skips /ImageMask due to qpdf
implementation, which affects many files.
