fix: properly handle password protected xlsx (#4057) ...

### Issue
Attempt at partitioning a password protected errors results in an
obscure exception
> Can't find workbook in OLE2 compound document

### Solution
Utilize [msoffcrypto-tool](https://pypi.org/project/msoffcrypto-tool/)
package (MIT License) to load XLSX file and check whether it's
encrypted, if yes throw an `UnprocessableEntityError` exception
detailing the reason for rejecting the file.
