As a user, I want generic image to permit upload of RAW, NEF and DNG formats. For the UI this involved permitting us to add the two extensions. This is currently in code and cannot be set by configuration.

The derivatives route needs to provide a conversion to JPG and JPG 2K, and Djatoka must be able to handle the type conversions for the viewer. The users must be able to download the OBJ in the original format.

FITS should be checked that is correctly can identify the original format.
