Add Direct Stream Digital/Transfer to mime types

Direct Stream Digital/Transfer (`.dsf`) files have MIME type
`application/octet-stream` but they're audio so `audio/something` is
more useful for rifle.

Scope also runs `mediainfo` and `exiftool` for miscellaneous `audio/*`
files but we can't match on MIME type here so I added a similar clause
in `handle_extension`.
