Seperate ESlint config package?

Since slothpixel/core and slothpixel/ui use the same ESlint rules, it would make sense to store them in a separate package.

I don't see the benefit of this to be honest, the configuration rarely changes.

The motivation is so that all of the dependencies can be synchronised.
