          A map of room ID to a map of `state_key` to an empty object.
          Each entry references a specific `m.room.image_pack` state event
          that the user has enabled globally.

          A room ID present as a key but with no `state_key` entries (i.e. an
          empty inner object) currently has no defined meaning.

          Clients SHOULD be aware that the user may not be a member of a room
          referenced here, thus the client will not be able to access any images from the
          pack. Clients MAY present appropriate UI to handle this case.

            The bottom-level object is reserved for future use. Clients SHOULD treat it 
            as opaque and preserve any unrecognised properties when modifying this event.
