GroqLM integration issue

[k2ai]

I identified GroqLM integration issue due to syntax error in below file.

https://github.com/stanfordnlp/dspy/blob/main/dsp/modules/groq_client.py

There is an issue found in line number 67 and 69

CURRENT CODE :

def log_usage(self, response):
        """Log the total tokens from the Groq API response."""
        usage_data = response.get("usage")
        if usage_data:
            total_tokens = usage_data.get("total_tokens")
            logging.debug(f"Groq Total Tokens Response Usage: {total_tokens}")

RESOLUTION:

def log_usage(self, response):
        """Log the total tokens from the Groq API response."""
        # usage_data = response.get("usage")
        usage_data = response.usage
        if usage_data:
            # total_tokens = usage_data.get("total_tokens")
            total_tokens = usage_data.total_tokens
            logging.debug(f"Groq Total Tokens Response Usage: {total_tokens}")
