Documentation for API Options

When reading the [API Docs](https://github.com/ollama/ollama/blob/main/docs/api.md#request-7) many options are listed with no visible explanation for what they do. The only explanation I could find [here](https://github.com/taketwo/llm-ollama/blob/40c66002a449cd52da2dbe91ea356b59e76bc9a5/llm_ollama.py#L45-L101) explains some, but more advanced ones are not explained anywhere it seems. Since I am to make Langchains ChatOllama more feature complete, I require these explanations for the necessary doc-strings.
