How can I get a signal accuracy ? #61

Hello !

I am trying to find a function that can tell me the accuracy of the signal.

At first I thought that TinyGPSPlus::distanceBetween() should do the trick, but that function does something else.

Is it possible to get signal accuracy ? Thank you !

The HDOP value is some indicator on the accuracy of the received signal. It is the standard deviation in meters. (99 if no fix)

Thanks @TD-er. @GeorgeFlorian, are we good?
