[aprssig] Cool new sensor

[Scott Miller]

If it's a multi-axis magnetometer, that would probably be a better way 
to measure wind speed than the accelerometer.

I've been meaning to try 3D printing a clip-on cup anemometer holder for 
my phone.  The anemometers I've got have magnets to trip reed switches 
and could probably be picked up pretty easily by the phone's magnetometer.
