Horizontal wind direction
Indicated in degrees, from 0 to 359, with respect to the WindMaster North marker.
In fixed field mode and when the wind speed is below 0.05 metres/sec, the direction will not be calculated, but the last
calculated direction above 0.05 m/s will be output (the threshold of 0.05 m/s is the default setting; it is user-
configurable).
