Island Life

update the game for 1.18

this includes the 1.03 fix

unfortunately the world generation settings changed significantly and migrating the old to the new was proving problematic.

I did get it working with a more vanilla method (which is actually good as it will likely work in future versions of minecraft) and I was able to find another larger body of water to center the player on but the terrain was not forthcoming with a lone island like before. but fear not! I added an island via fill commands in the ocean.... so you know... an island. 

This change is NOT compatible with prior versions. if you upgrade your data pack it will likely break the game. so unfortunately if you decide to play on 1.18 you will need to start over with this version.
