Easy Harness

This datapack simplifies the crafting of a `harness`. Crafts are demonstrated in the gallery.

All changes: - `Harness` crafting is `Shapeless` - Can use any type of `glass` (except `tinted`) - Note: Using `stained glass` does NOT affect the harness texture in ANY way - In the harness craft, you can also use a `dye` to immediately create a harness of the selected dye's color - Also adds a craft for a `white harness` from `strings`, because 4 `strings` = 1 `white wool`
