Self consumption predictor

Browse Source 
* Inverter: Self consumption interpolator for better discharge_hour results
 * Small penalty when EV 100% and charge >0
 * Price Forceast (use mean of last 7 days instead of repeat)
 * Price Prediction as JSON simulation output, config fixed electricty fees configurable + MyPy & Ruff
