Current Situation

The initial handshake of a websocket connection can cause additional latency. It's sometimes more performant to utilize only one websocket connection per client.

Proposed Actions

Refactor consumer.py and our client code to utilize a single websocket per client. This will likely require changing our websocket's URL routing schema.

We might want to make this option configurable via REACTPY_SHARED_WEBSOCKET, since the old behavior has the potential to be more performant when using multiple ASGI workers.

Alternatively, if this feature is optional then perhaps this might be better developed as a separate SharedReactPyConsumer websocket.
