fix(groq_client): corrected attribute access in log_usage

[matte0fabr0]

Overview

This pull request addresses critical issues in the groq_client module that previously rendered the package non-functional. Specifically, it resolves an AttributeError that was blocking all operations within the module.

Changes Made

• Corrected attribute access within the log_usage function to use dot notation instead of attempting dictionary access on a Pydantic model object.
• Ensured proper error handling in scenarios where expected attributes are missing in the response object.

Why These Changes Are Necessary

Prior to these changes, attempting any operation involving groq_client would lead to an immediate failure, thus preventing any functionality tests or further integration tests from being conducted. These changes restore basic operational capabilities to the groq_client.

Additional Notes

• While full integration testing was not possible due to the initial non-operational state of the module, basic manual tests were conducted to ensure that the module can now perform its primary functions without crashing.
• Further comprehensive testing should be implemented to ensure all functionalities are performing as expected under various scenarios.

Recommendations for Further Testing

• Implement unit tests covering new code paths introduced by these fixes.
• Conduct comprehensive integration tests to ensure all parts of the system interact correctly with the updated groq_client module.
