Refactor get_forecast_for_future_hour to return dictionary instead of…

… JSON string

- Refactored the get_forecast_for_future_hour method in class Location to return a dictionary directly instead of a JSON string.
- Bumped the version in setup.py to 1.1.0rc6 to reflect these improvements and changes.

This change improves the design of the Python package, making it easier to work with in other parts of the application and reducing potential errors related to JSON string handling.
