Add a connection status hook (discussion required)

[nexxai]

Problem

I want to be able to determine the current status of my connection to Reverb. As it stands there isn't currently a way to reliably retrieve this status.

Proposed Solution

I have added a useConnectionStatus hook that returns the current status, fetching it from the existing Pusher and Socket.IO libraries behind the scenes.

Notes

I am not currently sold on the return values as strings, but I couldn't come up with anything better that clearly represented the various states. I am very open to alternative suggestions; I just wanted to get something out there so that we could start the discussion.

This looks super useful, thank you! I'll give this a proper review after the new year and let's do it up 👍

This looks great, thank you! I ended up removing getConnectionStatus, users can just use echo().connectionStatus(). I also updated the useConnectionStatus hook to subscribe to status changes so that the hook reports changes in real time.
