Retrieve VisionStatus in the superstructure

This will let us access the VisionStatus message from several parts of
the superstructure. Using FetchLatest() within several parts of the
code within the same binary would cause some logical errors that I'd
rather avoid. I want to access the VisionStatus in the Hood and the
Turret for automatically selecting a good shot angle and shot power.
