Introduce `date_from_file_object` to `partition*` functions, by default set to `False`. If set to `True` and file is provided via `file` parameter, partition will attempt to infer last modified date from `file`'s contents otherwise last modified metadata will be set to `None`. --------- Co-authored-by: Filip Knefel <filip@unstructured.io> Co-authored-by: Ronny H <138828701+ron-unstructured@users.noreply.github.com>
