ccc2302b - feat: add the ability to specify a custom OCR besides the ones natively supported (#2462)

feat: add the ability to specify a custom OCR besides the ones natively supported (#2462) This is nice to natively support both Tesseract and Paddle. However, one might already use another OCR and might want to keep using it (for quality reasons, for cost reasons etc...). This PR adds the ability for the user to specify its own OCR agent implementation that is then called by unstructured. I am new to unstructured so don't hesitate to let me know if you would prefer this being done differently and I will rework the PR. --------- Co-authored-by: Yao You <theyaoyou@gmail.com> Co-authored-by: Yao You <yao@unstructured.io>
