End update

Completely overhaul the end in one go. Something similar to 1.16 but with end. There could be new strucutures, more difficult to beat bosses (its the End after all and all players will have end-game gear by the time they get there), maybe even new wood types. I think it would be better to do that in one go, because it would add excitement about the update from the community rather that divide it into a lot of smaller updates.
