Happier Ghasts

Happier Ghasts adds the Dried Ghast, Ghastling, and Happy Ghast before 1.21.6 releases! In the future and possibly in 1.21.6, this mod may receive more content/revamps.

- Dried Ghasts now generate as part of Nether Fossil Structures. - Dried Ghasts turn into Ghastlings after 20 straight minutes of being submerged underwater. - Ghastlings will follow other friendly mobs as well as the player. - Ghastling growth can be sped up using Snowballs. - Happy Ghasts can equip a harness, enabling players to fly on them. - Happy Ghasts will follow players holding a Snowball, or a Harness if they aren't already wearing one.
