[feature] Add source of weather file in input file

Summary

Add the source (Agri4cast, PVGIS, etc.) of weather data in the INPUT/SCENARIO yaml file so the code knows how to parse the data file.

Current behavior

None.

Desired behavior

Program a parser that adapts to various known weather data file formats (Agri4cast, PVGIS, etc.).

For example, the current config entry:

WeatherFileName:
   Value: Chanco_Chile_WD
   Type: string
   Definition: Name of the hourly or more precise (10 min or 15 min) weather data csv file (pay attention to the format it should have) if WeatherDataOption is 2

becomes:

WeatherFile:
   Value: Chanco_Chile_WD 
   Type: string  
   Source: [Agri4cast, PVGIS, custom]
   Definition: Name of the hourly or more precise (10 min or 15 min) weather data csv file (pay attention to the format it should have) if WeatherDataOption is 2

Sources
