Add grc subdirectory with component files

[Arithmeticus]

There is a grc.trainddata file, but no corresponding /grc subdirectory with the build files. Could that be supplied? Or is there a safe way to split a .traineddata file into its constituent parts?

See https://ancientgreekocr.org/

I began my quest from that site. But the @nickjwhite git repos lack the requisite Tesseract files that are in all the other langdata subdirectories. Even if the files are somehow at ancientgreekocr.org, the tesseract langdata repo should have a /grc subdirectory populated with the build files.

Thanks for answering this @Shreeshrii.

@Arithmeticus, note that the files in the langdata repository are designed to be used as input to tesstrain.sh from tesseract's training/ directory, which is why some of the files you may be expecting such as .inttemp aren't present. That is the same with all of the langdata directories.

There will be grc source files in the next release of langdata.
It will be missing desired_characters and forbidden_characters unless you would like to contribute some...
