Resolves #397
This PR migrates from the "function calling" paradigm to the "tool calling" paradigm. The main difference is that previously the model could only call a single function/tool at a time, whereas now the model can call multiple tools in a single request.
Currently, we only support tool calling with OpenAI's chat models. We will soon add support for tool calling with other providers (GoogleAI and Mistral).
