Reset for Cata Classic

[yoshimo]

On May 21st 2024 we will have a new classic expansion, cataclysm going live.
Since the shattering changes a lot around and we get access to more quest data in the api.
I think we should start over fresh and split the Wotlk State into its own submodule.

I will see what we can do in this area.
