 ** For normal configuration, just set the shunt maximum current and millivolt registers.  Shunt_Cal is calculated as needed based on those values.  For fine tuning calibration, the SHUNT_CAL register can be written to/adjusted.  Once a register is set, it is stored in EEPROM and used when shunt is powered up.
