DROID to additionally provide info on format type/classification?

[Dclipsham]

Suggestion from DROID user session - Might be useful to display 'Classification' within the DROID data export too, e.g. to more quickly see that a particular file/file format is of type xxx. Would require modification to signature file generation routine to expose that information from PRONOM within signature file, and then for DROID to make use of it. NB classification is currently 0-* - see e.g. https://www.nationalarchives.gov.uk/pronom/fmt/199
