Consider disabling OpenMP alltogether for Tesseract

For maximum throughput you might consider compiling an optimized Tesseract without OMP support. That's faster than using code with OMP support and disabling it. In a first step I suggest to try the latest Tesseract from PPA (https://launchpad.net/~alex-p/+archive/ubuntu/tesseract-ocr-devel?field.series_filter=focal) and compare the throughput.
