Return multiple choices

Describe the solution you'd like
Thanks a lot for making this library, it's been super helpful! I am working on a text classification task and I wanted to get multiple parsed responses from a single client.chat.completions.create call using OpenAI's n parameter.

The following would only parse the first completion I believe:

client.chat.completions.create_with_completion(
        model="gpt-3.5-turbo-0613",
        response_model=SinglePrediction,
        messages=[
            {
                "role": "user",
                "content": f"Classify the following text: {data}",
            },
        ],
        n=3,
    )

How would you recommend going on about it? Thank you!

I think we can create a overload that does this thanks for the new sdk

Will experiment with overloads.
