We are currently solving the following issue within our repository. Here is the issue text:
--- 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.
