Addresses 1. and 2. of #217.

The code on the UI side to parse the schema could look like

from panel.widgets import EditableIntSlider

from ragna.assistants import Gpt35Turbo16k


def make_panel_widgets(schema):
    widgets = {}
    for name, parameter in schema["properties"].items():
        type_ = parameter["type"]
        if type_ == "integer":
            widget_cls = EditableIntSlider

            fixed_start = parameter.get("exclusiveMinimum")
            if fixed_start is not None:
                fixed_start += 1
            else:
                fixed_start = parameter.get("minimum")

            fixed_end = parameter.get("exclusiveMaximum")
            if fixed_end is not None:
                fixed_end -= 1
            else:
                fixed_end = parameter.get("maximum")

            kwargs = dict(fixed_start=fixed_start, fixed_end=fixed_end)
        else:
            raise Exception

        widgets[name] = widget_cls(
            value=parameter.get("default"),
            name=parameter.get("title"),
            **kwargs,
        )

    return widgets


# Just for demo purposes
# This schema would come as part of the /components endpoint
schema = Gpt35Turbo16k._protocol_model().model_json_schema()

print(make_panel_widgets(schema))
