Wrong handling of (antenna related) position offset in V2

[mrksngl]

Method SurfaceOperationalStatusV2Msg.hasPositionOffsetApplied() throws, saying that V2 does not have a POA.
While it is true that there is no longer a single flag, we therefore have the much more detailed GPS Antenna Offset, see also method getGPSAntennaOffset. According to DO-260B, the position offset is applied if the longitudinal offset is 1, i.e. if getGPSAntennaOffset() & 31 == 0x1.
Now ED-129B even goes one step further and defines POA as getGPSAntennaOffset() == 0x1, i.e. additionally to the above, lateral offset must be set to "No Data".
