Subject: utils: Deny positional options in uhd_image_loader
This change prevents invalid positional options from being accepted into
uhd_image_loader. Previously, if a user forgot to specify the option
type, uhd_image_loader would proceed and look like it succeeded, but the
intended image may not have been loaded.
