Updated Readme for OCR Dependencies
Added tessdata to gitignore
Added OCR Testing and fixed some things

Created a new class Dir for all the testing Directories

Added a new OCR Test + means of automatically checking if it is correct

Switch from Tesseract Only to Tesseract+Cube for more Accuracy but
trade off is it runs close to 20x slower. 400ms -> 9sec

Changed the Filter to disable Emboss Text for now (might renable)
