Reverse Manhunt

nerfs:
hunters glow from 32->24 blocks away

new mechanics:
- while underground (below y=32), you'll get heartbeat sounds if there's a hunter in a 48 block radius to make hunters feel more scary, but also warn you
- endermen in the overworld and nether will give you gifts as you pass by, but removed their drops on kill, endermen can give you items as follows:

• 20% chance for 4-7 end stone
• 20% chance for 1-3 ender pearls
• 30% chance for 3-6 chorus fruits
• 10% chance for 1-3 obsidian
• 7% chance for an emerald
• 7% chance for a dragon heart fragment
• 3% chance for a diamond
• 3% chance for a weak dragon heart

other changes:
- slightly cleaned up and optimized the datapack code by putting similar commands into separate functions (to not repeat the same if/selector operations)
- fixed end crystals not healing friendly dragons properly
- increased default FOV and reduced default FOV effects in settings
