[time-nuts] Measuring coax temperature coefficient with a TICC

On something like a 500’ spool of coax, the question will always be “what temperature is it where in the spool”. A single sensor will
only give you precise information if the temperature ramp is *very* slow (as in days …).

Currently my environmental sensor code only does two channels of temperature. I am going to build a board with an ATMEGA 328 chip and BMP280 for humidity and pressure along with support for a couple of temperature sensors (should be able to do type K thermocouples and RTD1000's)
