Request: Expose socket messages as global events

[finite2]

The websocket logs messages to the console here but does not provide a way to listen out for these events from code external to this client.

In particular if a match is requested on the splinterlands website the match will emit an event here but cannot be interacted with because splinterlands.get_match() will return null here

I would like to be able to listen to and thus react to these events. A simple way to do this would be to dispatch events to the window which seems to be acceptable since it is done here
