tesseract: make sure tessdata default is version specific, e.g. tessdata4 #1
Description
After initial installer tests this popped up:
we must ensure that any tessdata install (which will be huge for tesseract 4./5.)) DOES NOT collidee with the old tesseract 3 data directory in Qiqqa.
One of the easiest ways to accomplish this under all circumstances is make the default tessdata directory version-specific, e.g. tessdata4 or tessdata5 instead of tessdata.
We could also consider using a engine-algorithm specific tessdata, e.g. tessdata-lstm but that would be a little more obscure to users going through their setup directories...
