James R. Barlow 4124889f36 Don't generate PDF/A-1b with object streams 
Acrobat insists that PDF/A-1b should not have object streams.
Other programs like veraPDF disagree with this restriction, but
we can accommodate Acrobat so we will.

Also add more tests around this.

James R. Barlow 064f935699 Fix page rotation regression 
Page size fixes in commit b26749 did accounted for a "kept" rotation,
but not a corrected rotation.

Fixes #730.

James R. Barlow 91aa175602 Consider text when determining page raster DPI 
Previously if we found vectors of any sort on a page, we would bump
the DPI up to 400. We did nothing
about pages with text. As a result,
pages with a low image resolution
and printable text would have the text downgraded to image
resolution when --force-ocr was used.

We don't try to determine if the text is visible or invisible OCR text, since
that is a slower test. --redo-ocr would improve such cases anyway.

James R. Barlow b267494e4a Create raster PDF pages to match input page size 
Previously we produced a raster image, then multiplied image width
by DPI to get the page size. However if there is rounding the
page size may not match exactly. In this modified approach we
constrain the page size to match.

James R. Barlow d372f1f7fa Remove "skip page" from tesseract interface 
Breaks tests/test_main.py::test_tesseract_missing_tessdata because
conftest.py does not update options.tesseract_env before testing options
for some reason, and tesseract.has_textonly_pdf raises an exception
instead of returning False as the test assumes.

James R. Barlow 991db17fde Remove Ghostscript-based text extraction 
While faster than Python based methods, we've outgrown the limited
amount of information Ghostscript provides with this feature, and it
repeats an analysis we have to do anyway to learn what images are
present.
