Tess 3.03's has various quality problems like wrong DPI that are fixed
in Tess 3.04. Idea here is to introduce an option to let OCRmyPDF
select the rendering backend based on the options and system.
However, we're not ready for tesseract as the main renderer.
Setting pdf-renderer to tesseract does not pass all test cases, mainly
the one where --tesseract-timeout is triggered, and some others.
