Awattar Price changed to more precise value; if SoC=0 discharge =1 forced. Exp Avg for siple Price Forecast

* Discharge Mask Bug, Tests updated, simple Price Forecast with linear weighting
 * Price Forecast with linear weighting, last value = highest weighting Discharge enforce when soc = 0 -> mask bug
