Add Calcite Slabs, Stairs, and Walls for Builder Palette Consistency

Hello Developers I'm suggesting a simple Quality-of-Life improvement for builders: Please add craftable Calcite Slabs and Calcite Stairs (and a Calcite Wall block, if possible). The Problem: Calcite is a beautiful, smooth, off-white decorative block found in Amethyst Geodes. It is currently one of the only aesthetically pleasing mineral blocks that is missing basic building shapes. This means builders can only use it for solid, flat walls, which limits its use in large architectural projects. The Benefit: Consistency: Adding these variants would bring Calcite up to speed with almost all other major stone and mineral blocks (like Quartz, Diorite, and Granite), which all have full shape sets. Palette Variety: Calcite offers a unique, slightly warmer tone compared to the very bright, pure white of Quartz. Builders need this subtle difference to create better contrast and detail in their creations (like roofs, trim, and elaborate flooring). This is a small addition, but it would be a huge benefit to the building community and make a beautiful block truly usable. Thanks for considering this!"
