6a6a572069 dfrec: Initial implementation
This module implements support for the DFRobot EC (Electrical
Conductivity) meter.  It relies on the use of the DS18B20 UPM C module
for temperature gathering.

It has a pretty complicated calibration procedure which is somewhat
documented on the DFRobot wiki.  Functions have been added to support
changing the various coefficients as desired.
