config: Initialise a new websocket-driver client on new config

Add a new `make-config` function to construct a `config` object. This
creates a new websocket-driver client and stores it in the `ws-client`
slot in the `config`.

Before this, I thought about using a writer method on the `socket-url`
slot that creates a new client. This didn't work in `make-instance`
though. Perhaps there's a way to have the `:initarg` use the writer, but
I'm not sure.
