Re-implement Authors package from zero in the workspaces

[fraxken]

Current authors package require a complete rewrite (from zero).

That's what I was trying to do in: https://github.com/NodeSecure/authors/pull/52 (but kinda failed because it was more complicated that I imaginated).

The domain-check package should also be merged here (I don't think we need a dedicated workspace for it however).

One of the main goal is to simplify the integration with Scanner. But it will also drastically reduce the maintenance required.
