Use debug module with stdout/stderr

[ibc]

I always use the Node debug module as follows:

https://github.com/versatica/mediasoup/blob/v3/lib/Logger.js

It provides a constructor to set a sub-namespce (optional) and 3 methods:

• debug(): prints to stdout.
• warn(): prints to stderr and adds :WARN: between the "app name" and the sub-namespace.
• error(): prints to stderr and adds :ERROR: between the "app name" and the sub-namespace.

Interested?
