Better Pyramids & New Structure

In this datapack Desert Pyramids is changed to now have room like mazes

More rooms/treasures will come in the future

The default Treasure room can still spawn

New Structure can now spawn, and void is extended but bedrock layer is the same

FYI: There might be bugs when it spawns in the world, but have fun :D

FIYY: Prehaps more/new structures will be added
