QUirk handled in git head.

Also patched for some other nonstandard behavior.  Their doc details
other nonstandard GAGSV and GNGGA, behavior not patched.

I expect there to be other problems with their firmware.

Sloppy work on their part.

Please test, and file a bug with Jackson Labs.  Their doc shows
they do not understand how NMEA wants this done.
