Reference Point Offsets Packet

The reference point offsets packet can be used to adjust the measurement point that
all data is referenced to. By default all the values of this packet are zero and the
measurement point that all data is referenced to is the centre of the Spatial FOG Dual
unit. The primary reference point offset can be used to adjust the measurement point
to a different location on the vehicle. The primary reference point offset applies to all
data output including NMEA etc as well as heave point 1. The other heave point offsets
apply only to heave points 2-4 in the Heave Packet.
