ref: Allow passing custom prompts to Groq methods

Rudimentary implementation currently. Would probably ultimately help to
have a 'prompt' domain model which can be used something like this:

Prompt(type=Prompt.SUGGESTIONS).leaning("left").current(2025).area("politics").view("American")

That way it would be easy to build your own prompt.
