- Adds ability to set bus - needed for Raspberry 4 because autodetection fails on this board
- Sets default shunt_ohms to 0.1 (instead of 100) - the almost always used R100 has 0.1 Ohms, not 100 Ohms.
- Optional i2c_bus_num if autodetects fails (often on Pi4) - shunt_ohms defaults to 0.1 (equals to R100, which is used in almost all boards)
