Support for OpenAI - o3-Mini Model

[niketrk]

With a reasoning model, the result can be better.

While trying to use that, it gives an error because tabby sends "presence_penalty" parameter which is not accepted by OpenAI o3-Mini model.

If we can make it supported via making changes in "async-openai", if certain models are used, some parameters are masked before the request is sent to openAI.
