Type handlers

[taoufik07]

Hey,

Channels allows code decoupling by dispatching messages to handlers chat.join triggers chat_join.

I've made something similar while playing with asyncio and decided to try to implement it in nejma (checkout this branch).

Usage (a gist with the whole app)

@app.websocket_route("/ws")
class Chat(WebSocketEndpoint):
    encoding = "json"

    async def on_receive(self, websocket, data):
        ...
        group = f"group_{room_id}"

        self.channel_layer.add(group, self.channel)
        
        await self.channel_layer.group_send(group, {
            "type": "hello.world",
            "message": "Hello world !",
        })

    async def hello_world(self, payload):
        await self.send(payload)

I wanna know what you guys and if it should be in master ?

it's integrated with starlette for now, it's just a test and the implementation need to be reviewed to have loose coupling and reusable components.
Also feedback about the implementation will be appreciated.
