Wool Additions

# Wool Additions Backports 26.3 Snapshot which added Sittable Cushions, Wool Stairs, and Wool Slabs (I plan to add the sleeping bag in a later version). ## Wool Stairs > - Wool stairs can be crafted with 6 wool of the same type to get 4 stairs > !(https://cdn.modrinth.com/data/cached_images/3a876d2e4e1a0f25664caa77998403003e2ea6c0.png) ## Wool Slabs > - Wool Slabs can be crafted with 3 wool of the same type to get 6 slabs > !(https://cdn.modrinth.com/data/cached_images/d0e64d0eef68686b54125b89a77b178c8408901e.png) ## Cushions > - Cushions can be crafted with 3 wool slabs of the same type. > - Cushions can be placed inside of blocks such as stairs, slabs, etc. and also ontop of blocks > such as trapdoors, amethyst clusters, buttons, etc. just like in 26.3 > !(https://cdn.modrinth.com/data/cached_images/d573d2a65a89db6ffa3a4c80ce94157fa03e6ab4.png) ## Planned Features > - I plan to add the Hay Sleeping bags which was also added in the snapshot (maybe with a config to change between Hay and normal Wool as 3 blocks of Hay for 4 temp use sleeping bags seem a bit expensive)
