No Double Slab Placement

This mod adds a toggle which prevents the player from placing a slab-block in a place where it could form into a double slab block.

- The toggle is triggered through a configurable key-bind. - `U` key is set as the default keybind for toggling the feature on and off - The key-bind can be configured from the vanila key-binds option menu

By default it is toggled on, to disable the mod/feature and allow the placement of double slabs you must toggle it off yourself with the key-bind
