Ignore talker IDs

[themadsens]

The first two letters of the sentence type is the "Talker ID"
These can be safely ignored for the sake of the sentence type and should be too.
For instance, sentences sent from my YDNR-02 NMEA bridge uses "YD" as talker id

It's better to check all of the part than ignoring a part of the sentence, i.e. talker id, before processing; the communication between MCU and receiver might be very noisy.

Why don't you use the module by starting like this?

from micropyGPS import MicropyGPS
gps = MicropyGPS()
gps.supported_sentences = {'YDRMC': MicropyGPS.gprmc, 'YDVTG': MicropyGPS.gpvtg}
