🔍 Description

Implement Realtime V2 Serializer

Connected to supabase/realtime#1606

What changed?

New serializer version 2.0.0 (experimental for now) supported which has:

• Two new special types of messages: user broadcast and user broadcast push
• Allows binary user payloads
• Reduces the amount of JSON encoding involved server side

The default version is still 1.0.0 while 2.0.0 can be tested so real change.

Why was this change needed?

Binary payload support & more streamlined broadcasts for server side handling
