Big Cranes and other big structure

Request from Discord (Rash Maps (Yerrash)): "We have these really nice cranes on the Mason stamp, but we don't have crane for the dwarven package, the other crane options don't really fit the whole idea of dwarven or a more "artificer" type of culture, specially when you want big cranes. Having individual cranes in the Dwarven Set would be really nice.

Also, would be good to see other big structure building tools, like temporary stair or temporary wood structure reinforcements. Which is commonly seen supporting dwarven building that are ongoing. "
