Add Weekly Forecast for a particular location entered by user

[lavishabhambri]

Problem

In our weather website, the user cannot view the future predictions of the weather week wise for a particular location.

Importance

The weekly predictions will help the user to analyse & plan the future events accordingly. Moreover, forecasting can also help to save lives and minimise property damage. It's also crucial for agriculture, allowing farmers to track when it's best to plant or helping them protect their crops. And it will only become more vital in the coming years.

Solution

• Add the weekly forecast from the present date about a particular location which is entered by the user.
• Try to extend the functionality to any no. of weeks from the present date.

@lavishabhambri and @niyoj if you can coordinate with @SudhanshuBlaze's team since they're doing hourly forecasts and y'all could help each other.
