Nikos Livathinos	3be2fb581f	feat: Introduce automatic language detection in TesseractOcrCliModel (#800) ... * feat: Introduce automatic language detection in tesseract_ocr_cli model. Extend unit tests. Signed-off-by: Nikos Livathinos <nli@zurich.ibm.com> * docs: Add example how to use "auto" language with tesseract OCR engines Signed-off-by: Nikos Livathinos <nli@zurich.ibm.com> * fix: Refactor the TesseractOcrModel and TesseractOcrCliModel to validate if the auto-detected language is installed in the system and if not fall back to a default option without language.
