Description

Is your feature request related to a problem? Please describe.
Unstructured supports most Excel file formats (xls, xlsx) but documents that include macros use the .xlsm extension and are not recognized by Unstructured.

Describe the solution you'd like
Unstructured should be capable of ingesting xlsm files as if they were regular Excel files but without macro execution.
My cursory research indicates that there are no differences with from regular Excel files besides the inclusion of macros.

Describe alternatives you've considered
An alternative would be converting such files to xlsx before sending them to Unstructured but it would be nice if those could be ingested as is.

Research direction

Start by comparing how Unstructured recognizes and ingests xls and xlsx files; the issue names no files or tests. Confirm that .xlsm files are accepted as regular Excel documents without executing macros, and add coverage for that behavior.
