Add option to ignore file extension

[dstutz]

Curious if a new PoijiOption could be added to disable the file extension check?

Working on a web application where we have a temporary file upload service that takes the file, writes it to disk with a filename based on a generated ID and returns the ID to be used by other parts of the application to store the file in a final way in which case the original filename would be stored as metadata, or the file is discarded. I am trying to process a spreadsheet uploaded to that temporary area, since I don't want to permanently save it, and am hitting that exception.

com.poiji.exception.InvalidExcelFileExtension: Invalid file extension (), expected .xls or .xlsx

Hi @dstutz ,

Thank you for bringing this feature up! I think, it's doable. We can have this available in the later versions of Poiji.
