[libtesseract] output of get_available_builders() is incomplete
Created by: wwqgtxx
I see the code of
https://github.com/openpaperwork/pyocr/blob/master/src/pyocr/libtesseract/tesseract_raw.py#L381
https://github.com/openpaperwork/pyocr/blob/master/src/pyocr/libtesseract/init.py#L110
It's showed the libtesseract was supported the numeric mode,but why in get_available_builders
not allow us use DigitBuilder
?
