Support for thinking in ollama models like granite3.2

[Eloitor]

It would be nice if it was possible to enable thinking with ollama granite3.2 https://ollama.com/gabegoodhart/granite3.2-preview

Generation: To enable thinking, add a message with "role": "control" and set "content" to "thinking". For example:

{
    "messages": [
        {"role": "control", "content": "thinking"},
        {"role": "user", "content": "How do I get to the airport if my car won't start?"}
    ]
}
