Implement Tesseract as an alternative model that can be used in backend

[zdeveloper]

Currently our OCR Pipeline only allows for hugging face models. Implement Tesseract as an alternative to the HuggingFace Models

• Ensure Tesseract invokes segmentation logic and processes each segment accordingly.
• Ensure Tesseract is implemented as an alternative to HuggingFace models such that each model/approach can later be changed and/or benchmarked appropriately.
• Ensure we can switch to the HuggingFace Models if needed.
