Handling negative geoid values

[mendhak]

I have a GPGGA string where the geoid is below sea level:

$GPGGA,214213.00,3249.263664,N,11710.592247,W,1,11,0.6,102.2,M,-26.0,M,,*51

The parser doesn't match this, it jumps straight to the onFinished event in the handler.

This doesn't get matched by the GGA pattern. I think CAP_FLOAT needs to allow an optional negative sign?

Oh, that's what this issue is - heh, I just created a pull request to resolve this.

Would be nice if this could be added and updated to the library!
