Convert to v2 addon

[SergeAstapov]

As this addon provides only run-time functionality hence it's the great candidate for v2 addon conversion.
There is guide great Porting an Addon to V2 guide I suggest we follow.

My thought process of the next steps is to have PRs in the following order:

1. convert to monorepo
2. convert addon to v2
3. release new major v5.0.0

@snewcomer @cibernox do you have any thoughts, concerns? I can volunteer to work on those

Seems like a great idea!
