Relocate caffeine to fix conflicts with other mods/plugins

Pull Request

Description

When another mod/plugin uses Caffeine there can be a conflict, as both try to create an instance. This is resolved by relocating the dependency.

I have tested this locally and on a development server, it appears to have no change in behavior besides fixing the issue.

Are there any specific mod/plugin that had an issue with this?
I'll likely approve it anyways, I just want to see if there's anything else which doesn't relocate it.

The specific one I had an issue with was EcoEnchants (or more specifically their library called libreforge)
