Title: Implement JSONSchema Validation for Config File Loading

Description:

In order to ensure the integrity and correctness of our configuration data, we propose to implement automatic JSONSchema validation in the load_config function. This will verify that all required fields exist and that they are of the correct type, improving our application's robustness and error-handling capabilities.

Tasks:

1. Write a JSONSchema template that reflects the expected structure and data types in our configuration files.
2. Incorporate the JSONSchema validator into the load_config function to validate configuration data against the template.
3. Handle potential exceptions that may arise from validation failures, providing informative error messages to aid in troubleshooting.
4. Test the new load_config function with various valid and invalid configuration files to ensure correct operation.
5. Update relevant documentation to reflect the new JSONSchema validation feature.

Acceptance Criteria:

• A JSONSchema template is created that accurately reflects our configuration file structure and data types.
• The load_config function uses the JSONSchema validator to check configuration files.
• Exceptions from validation failures are handled appropriately and provide helpful error messages.
• The updated load_config function is fully tested with different configuration file scenarios.
• Related documentation is updated with information on the new JSONSchema validation feature.
