Patch:core:More Talker IDs other than GP accepted (#314)

NMEA messages starts with '$' followed by 2 digits that indicates
the Talker ID. The most common was GP for GPS, but now many modules
can use other satellites systems or even 2 systems at the same time.

Other Talker IDs are:
- GL:russian GLONASS
- GA: european Galileo
- BD: chinesse BeiDu
- GN: Global Navigation: a combination of 2 or more systems.
