New content:
• Stone cutters can process wood (planks→ half-bricks/stairs/fences)
• Stone cutters can peel logs

• The stone cutter can break down various blocks (coral, quartz, ice, drip stone, amethyst, etc.)
• The blast furnace can recover metal products as corresponding ingots per pellet
• The furnace can burn wool into dye
• Chests/Funnels/Shadow Boxes can be crafted using barrels instead
• Chain armor can be crafted using iron chains
• Deepslate can be converted from cobblestone in blast furnaces to achieve renewability
