Add an I2C isolator in between the lagopus/lemming board i2c sensors on the lemming board that we prevent short problem in case of water/ice infiltration in the sensors. Shorts of the I2C line introduce noise and mess with RTC and PWR management of the mote which leeds to varied serious problems.

To include on future version of the lemming board
