ZygZag's Endgame Expansion

Heavy behind-the-scenes changes that will hopefully streamline the process of adding new features.

Added Sculk Jaws!

• Spawn when sculk spreads and in the Deep Dark, same as Sensors and Shriekers
• Grabs onto any entity inside its hitbox
• Entities grabbed will slowly be drained of health, and the Jaw will create more sculk like Sculk Catalysts
• Players grabbed will have their XP drained first
• When powered with a redstone signal between 0 and 7, Jaws will not sap entity health or experience
• When powered with a redstone signal of 7 or greater, Jaws will not grab onto entities and will let go of anything currently grabbed
