Log-probabilities should not be turned on by default about fauxpilot HOT 1 OPEN

This is probably due to the alignment with the OpenAI API reference. In OpenAI logprobs default to null https://beta.openai.com/docs/api-reference/completions/create#completions/create-logprobs which I implemented in the model https://github.com/moyix/fauxpilot/blob/main/copilot_proxy/models.py

Before it was

num_logprobs = data.get('logprobs', -1)
want_logprobs = num_logprobs > 0

With the new logic, it will retrieve None and originally if that happened I would set it to -1 but I vaguely remember that -1 trigger something "weird". You might want to play around with this and set it to -1.

        num_logprobs = data.get('logprobs', -1)
        if num_logprobs is None:
            num_logprobs = 1
