This PR introduces `clean_pdfminer_inner_elements` , which deletes pdfminer elements inside other detection origins such as YoloX or detectron. This function returns the clean document. Also, the ingest-test fixtures were updated to reflect the new standard output. The best way to check that this function is working properly is check the new test `test_clean_pdfminer_inner_elements` in `test_unstructured/partition/utils/test_processing_elements.py` --------- Co-authored-by: Roman Isecke <roman@unstructured.io> Co-authored-by: ryannikolaidis <1208590+ryannikolaidis@users.noreply.github.com> Co-authored-by: rbiseck3 <rbiseck3@users.noreply.github.com> Co-authored-by: Roman Isecke <136338424+rbiseck3@users.noreply.github.com>
