Allow carpet dupers

Personally, I think carpet dupers should be allowed, would make maparts a lot easier to make. you could add a system where only like a few clumps of carpet items could be in a few chunk's radius at a time, so it wouldnt lag the server too bad. if you wanted you could have to have an active player there, so you couldnt make it afkable, to further prevent lag in case of chests overflowing
