add WebSocketConnection class

[m2es3h]

I have a use-case where I've been using the websocket adapter from stomp.py project (see stomp/adapter/ws.py in https://github.com/jasonrbriggs/stomp.py for reference).

I've recently switched to using stompman and added a WebSocketConnection class to support this use-case, based on your existing Connection class.

Known issue: no support for URL paths after the ws://hostname:port yet. Do I modify the existing stompman.config.ConnectionParameters, or create a websocket-specific ConnectionParameters? Not sure which way is preferred.

Hi! This seems mostly fine. I can accept the PR if you adjust some stuff:

1. Add optional-dependencies group and put websockets there so we can install it with: stompman[ws]
2. Document it in README.md
3. Add proper tests
4. Install just and run just command to ensure proper formatting, linting, etc

Too much hassle to create websocket-specific connection parameters. let's compromise and modify existing connection parameters

Also this new class should be in separate file so that import doesn't fail if you don't have websockets installed

I still need to follow-up with 3. Add proper tests, but I've implemented your suggestions above.

Test is flaky, but type checking fails

Great, CI is passing! Let’s also mention stompman[ws] in the readme
