  --- BEGIN ISSUE ---
  Easier websocket interface annotation
  Right now, to properly annotate a websocket endpoint you need to do this:
  
  ```python
  from sanic.server.websockets.impl import WebsocketImplProtocol
  from sanic import Request
  
  @app.websocket("")
  async def handler(request: Request, ws: WebsocketImplProtocol):
      ...
  ```
  
  That is not easy or intuitive.
  
  This would be much nicer:
  
  ```python
  from sanic import Request, Websocket
  
  @app.websocket("")
  async def handler(request: Request, ws: Websocket):
      ...
  ```
  
  We should just alias and put it inside `__init__.py` for convenience.
