Separate callbacks for on_process_result

[Makcal]

I have a dialog that can start several different dialogs, but is limited to have one on_process_result() callback. This is why to distinguish these calls I pass start_data in form of {"intent": "enter_name", "input": ...} and my callback looks like:

match start_data["intent"]:
    case "enter_name":
        # process input of the name field
        ...
    case "enter_text":
        # process input of the text field
        ...

This can produce long and complex callbacks. I wonder if there can be a cleaner way to process results. Thinking a while I've come up with two proposals:

1. Pass a callback directly in a dialog's call:

await manager.start(PromptSG.main, promt_params, callback=process_name)`

2. Use a decorator to mark a function as a callback for a particular dialog:

@dialog.callback_for(PromptDialog)
def process_name(start_data, result, manager)
    ...

In version 2.2 you can set on process result callback on window. This is not the same, but anyway, it can reduce size of function.

Yeah, that's not the same, however it would be great to have clear separation for a window, e.g. for buttons that start dialogs
