Stone Pistons that are slower, quieter, and easier to hide

A piston crafted from stone that reacts slower than a normal piston. It would make a much quieter noise that is harder to detect, which could come in handy for traps. When fully extended, the piston looks like a stone wall or some minor variation, making it easier to conceal. It could also be a feature in the archaeology part of the update, where you might dig up a room, find a switch under some gravel, and a wall opens up behind you to reveal either a trap or a chest. To craft one, you’d need a chain, some redstone, and the stone block of your choice. Sticky versions can be crafted with honey and a stone piston. It would also come in a few common stone textures. This would also be useful for some interesting generated structures- say, a cave wall in the Deep Dark that opens when a player makes too much noise, unleashing the Warden.
