Trapdoor (Core pack) without background

Request from Discord: " Can we please have a version of the trapdoor without the baked in black BG? A transparent part here would be nice. Or mask is transparent can't be achieved. I've been willing to ask for the this for a long time about the old asset. Now is the time. I feel like the floorboards one can see on the new one are more intrusive than in the previous iteration of the stamp. The previous version had pure black. It could work for wooden flooring, dirt, stone… Now it's gonna look really weird to see wooden floorboards down there if we're doing anything else than wood for the floor below."
