[Feature] use more available Solar API calls

[stan23]

The Solar API provides more APIs than this adapter is using.

These API calls are answered with data on my Fronius Symo 10.0-3-M:

used in this adapter	API example call
yes	http://fronius-ip/solar_api/GetAPIVersion.cgi
no	http://fronius-ip/solar_api/v1/GetInverterRealtimeData.cgi?Scope=System
no	http://fronius-ip/solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceId=1&DataCollection=CumulationInverterData
yes	http://fronius-ip/solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceId=1&DataCollection=CommonInverterData
no	http://fronius-ip/solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceId=1&DataCollection=MinMaxInverterData
no	http://fronius-ip/solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceId=1&DataCollection=3PInverterData
yes	http://fronius-ip/solar_api/v1/GetLoggerInfo.cgi
no	http://fronius-ip/solar_api/v1/GetLoggerLEDInfo.cgi
no	http://fronius-ip/solar_api/v1/GetInverterInfo.cgi
no	http://fronius-ip/solar_api/v1/GetActiveDeviceInfo.cgi?DeviceClass=System
yes	http://fronius-ip/solar_api/v1/GetPowerFlowRealtimeData.fcgi?Scope=System

These calls are not supported from my device and return no data, because I have neither a storage nor a meter:

used in this adapter	API example call
yes	http://fronius-ip/solar_api/v1/GetSensorRealtimeData.cgi?Scope=System&DataCollection=NowSensorData
no	http://fronius-ip/solar_api/v1/GetStringRealtimeData.cgi?Scope=System&DataCollection=NowStringControlData
yes	http://fronius-ip/solar_api/v1/GetStorageRealtimeData.cgi?Scope=System
yes	http://fronius-ip/solar_api/v1/GetMeterRealtimeData.cgi?Scope=System

The internal temperature can only be read by using this trick:
http://fronius-ip/solar_api/v1/GetArchiveData.cgi?Scope=System&StartDate=17.10.2020&EndDate=17.10.2020&Channel=Temperature_Powerstage

Maybe the adapter can be enhanced with the API calls that return useful additional data.

Please try out the newest Version V1.1. There the most datapoints are visible. If you need specific extensions, then just let us know the missing datapoints
