Create an adapter for pusher / socketi

[noam-honig]

The live query mechanism uses an adapter pattern to replace implementations. Currently, there's an adapter for Server Sent Events, and one for Ably - it'll be great if there's an adapter for Pusher/socketi.

Here's the ably adapter for reference:

Here are the docs on how to use Ably with remult:
