Increase charge pump frequency to 500 Hz
...
This change reduces the voltage drop with higher loads, for example if
both the solar and the load switch are on at the same time.

Make measurement usable
...
- Run ADC Calibration on startup (without calibration, there is a huge
offset error, making the current sensing unusable)
- Added calibration factors which allow to compensate for inaccuracies
in the circuitry (example: 1% tolerance transistors)
- Send measured values via RS485
