fixes #6

This works with current PyTrack. It should work for older Pyrack's as well. Those devices will see these attributes with blank values.

Add NavigationalStatus to _RMC() keywords list as per page 9 in spec.
Add GNSSSystemId to _GSA() keywords list as per page 13 in spec.
Add SignalId to _GSV() keywords list as per page page 15 in spec.

Hi Patrick I've changed your fix a bit to make it work on older versions to. Can you test it? it's in the fixfor4.10 branch. best regard André

Works on my board as well. This does feel fragile. I wonder if there's a way to determine the NMEA Version form the chip. I'll ask on the Quectel forum. For now, I'd go ahead and push this live as it works. 👍
