[TangerineSDR] Magnetometer current state

[Scotty Cowling]

Great progress, Dave!

Nathaniel, will this be usable by the Magnetometer testing volunteers 
that you have lined up? It seems that if remote users can acquire the 
data via a websocket connection, we have enough connectivity for a 
beginning array of a (few) dozen or so. How much security can we skip 
over just to get some testing done?
