Mistral API compatibility

[Onigam]

Instead of using OpenAI api I want to use Mistral AI api using the 8x7B model.

The only blocker with this code is the presence_penalty: 1 parameter in the index.js file, we just need to remove this line
to avoid OpenAI error 422 due to this Extra inputs not supported and permitted from Mistral API

I created a fork with this fix here

Now I'm using Mistral instead of OpenAI than is a lot cheaper
