Calcite and Packed Ice

Add new building blocks made from Calcite and Packed Ice.

For Calcite, add Calcite Bricks, Chiseled Calcite, Polished Calcite, stairs, slabs, fences, and other decorative blocks.

For Packed Ice, add Packed Ice Bricks, stairs, slabs, fences, and other building variants.

Why is this needed?

This would expand the variety of building blocks in Minecraft, make building more diverse, and give players more options for creating new structures and architectural styles. In addition, these new variants would help reduce the repetitiveness of builds and allow players to use Calcite and Packed Ice not just as basic blocks, but as full-fledged building materials.
