feat: allow passing down of ocr agent and table agent (#3954) This PR allows passing down both `ocr_agent` and `table_ocr_agent` as parameters to specify the `OCRAgent` class for the page and tables, if any, respectively. Both are default to using `tesseract`, consistent with the present default behavior. We used to rely on env variables to specify the agents but os env can be changed during runtime outside of the caller's control. This method of passing down the variables ensures that specification is independent of env changes. ## testing Using `example-docs/img/layout-parser-paper-with-table.jpg` and run partition with two different settings. Note that this test requires `paddleocr` extra. ```python from unstructured.partition.auto import partition from unstructured.partition.utils.constants import OCR_AGENT_TESSERACT, OCR_AGENT_PADDLE elements = partition(f, strategy="hi_res", skip_infer_table_types=[], ocr_agent=OCR_AGENT_TESSERACT, table_ocr_agent=OCR_AGENT_PADDLE) elements_alt = partition(f, strategy="hi_res", skip_infer_table_types=[], ocr_agent=OCR_AGENT_PADDLE, table_ocr_agent=OCR_AGENT_TESSERACT) ``` we should see both finish and slight differences in the table element's text attribute.
