RMC not calculated when SOG=0 and no COG available

[LeaseOnLife]

My SITEX N2K AIS with GPS does not put out a COG when at standstill. That seems to cause this plugin to not put out a RMC sentence.

Use case: I have some old wxtoimg sat-image receiving system that needs to have RMC as ground station location. When the boat is not moving, it fails to get the lat/lon, since no RMC is received

Could the need for COG be made dependent on having a SOG>0, otherwise just plug a zero into COG?
