Jon Trulson dcb4e83251 dfrorp: Initial implementation
This module implements support for the DFRobot Analog ORP
(Oxidation/Reduction Potential) Meter.

It requires 5.0 volts, but the more accurate the voltage specified (to
the constructor), the more accurate the meter (paraphrased from the
wiki).

// setCalibrationOffset(). Then reconnect the probe to the
// interface board and you should be ready to go.

// DO NOT press the calibrate button on the interface board
// while the probe is attached or you can permanently damage
// the probe.
