add Gnome villages

Ok with this idea the villages would spawn in two biomes, dark forest & jungle (make them rare to find). The villages in dark forests look like this: the houses are made from the giant mushrooms (specifically the red ones) they don't spawn with a golem and are not very large. In the jungles they are slightly larger and spawn branching off of large trees. Since the houses are in the air you have to do a simple parkour to get from house to house. Now for the Gnomes, they are around 1 1/4 blocks tall you can't breed them and there are 1-2 per house. You can trade with them but because gnomes tend to be magical creatures there trades are different. I mean in a way that you trade them say the dragon egg as well as an elytra and you will get an elytra that has triple durability and looks like ender dragon wings that will come with an achievement.
