### Summary Closes #1534 and #1535 Detects document language using `langdetect` package. Creates new kwargs for user to set the document language (`languages`) or detect the language at the element level instead of the default document level (`detect_language_per_element`) --------- Co-authored-by: shreyanid <42684285+shreyanid@users.noreply.github.com> Co-authored-by: ryannikolaidis <1208590+ryannikolaidis@users.noreply.github.com> Co-authored-by: Coniferish <Coniferish@users.noreply.github.com> Co-authored-by: cragwolfe <crag@unstructured.io> Co-authored-by: Austin Walker <austin@unstructured.io>
