Support separate UnitOfMeasure in DefaultUploadPage

• Version of CORE? Current

• Issue with Office, Lane, or both? Office

• Is this [mostly] a bug report, feature request, or question? Feature offer

I have a catalogue from a new vendor that loads very nicely with DefaultUploadPage.php with one exception: it has UnitOfMeasure in a separate column from Unit Size, which contains only the number. Would you be open to the addition of support for an optional UoM column which would be appended to Unit Size? Also in UpdateUploadPage.php. If so I'm happy to code and submit a pull request.

Sure, that sounds perfectly reasonable.
