To get some information about the currect accuracy of the GPS it would be good to have access to the HDOP measurement.

Maybe even a accuracy measurement value, by using HDOP * 1.8 (which is the Position Accuracy from https://learn.adafruit.com/adafruit-ultimate-gps/ )?

Add readHDOP and getAccuracy

Added a solution to issue particle-iot#15

Added two functions to get information about the current accuracy of the GPS.
Needed for example to do a Kalman filter of the signal or any other
signal processing.

The calculation of the accuracy is not done in any spectacular way,
just a multiplication of the positional accuracy, but it should at least give
a sense of what the accuracy is.
