WAMP router support for wss

[bradfordcondon]

Hello:

The WampConnectionFactory requires the dsn to be wamp or ws, with establishConnection using ws as the uri.

https://github.com/php-enqueue/wamp/blob/master/WampConnectionFactory.php

I'd love to make it easy to support wss instead of ws. The simplest way would be to simply make establishConnection and config protected instead of private so I can extend and overwrite it.

Alternatively, we could add a wss option in config to build the uri optionally with wss vs ws.

The issue

Edit to communicate why I want this:

I'm using a nexus WAMP router with an autobahn-hs frontend wamp client trying to talk to the enqueue wamp client. Because its via the web browser, I need HTTPS/WSS, which causes the Enqueue connection to fail at Thruway\Transport\PawlTransportProvider with "Trying to send an HTTP request tot an HTTPS server". Changing to wss resolves this.

I've prepared an MR adding wss parsing: happy to submit or revise based on your preferences.
