[Epic] waku relay (node)

[D4nte]

Problem

A near real time decentralized and secure communication protocol is needed to enable dapps, wallets and other apps (e.g. chat app) to use a decentralized infrastructure while maintaining an acceptable UX,.

Solution

Provide a JS library that allows developers to use waku v2 relay for near real time communication purposes.
Ensure the JS library is functional by including a suite of tests.
Demonstrate the usage of the API by building a CLI chat app that can communicate with the nim-waku example chat app.

For now, the solution can be focused on node support only. A separate issue will track browser support.

Acceptance Criteria

Tests

Demonstrate the following features as working in test:

• Publishing messages between js-waku instances js to js waku relay publish does not seem reproducable in test #7
• Publishing messages between js-waku & nim-waku instances
• Encoding/Decoding of Waku messages
• NAT passthrough support NAT traversal #12

Chat app
