James R. Barlow 54e74f84cc Remove special of TypeError from ruffus 
split_pages would still run if repair_pdf failed, for some reason.
Since we are no longer splitting pages this is vestigial.

James R. Barlow 76e7e8dbbb Replace several uses of str(path) with fspath(path) 
Helps make it more explicit. Did not do this to tests because use of paths
is more involved there.

James R. Barlow 324598e992 Remove helpers.universal_open() 
This helper function only had a single usage, this was always an awkward
way to support Python 3.5 that I'd forget to use.

James R. Barlow 8c84c515b6 Use Ghostscript for text region detection 
Ghostscript txtwrite seems to be quite effective at the task.

James R. Barlow 9608b22d34 Remove all uses of PyPDF2 except PDF/A check 
Leave PDF/A check alone for now, since pikepdf has no equivalent.

James R. Barlow b06ef03aac pipeline: use the resolution of the OCR image rather than recalculating 
(Recalculating would fail if the image is not centered.)

James R. Barlow 35cb416563 pipeline: remove fitz-based attempt to repair table of contents 
Prior to unsplit, if we were rebuilding the PDF we'd lose the
table of contents. With unsplit we keep the original file and patch
the table of contents as necessary, adn that works fine.
This remaining bit of code from PyMuPDF actually damages the
table of contents and removing it fixes the test suite. G'bye.

qpdf from appimage does not report its version with --version if renamed

where needed.
