Natural Absorption

1.16.5-1.0.0
- Rewritten for 1.16.5, primarily done by Sarinsa
- Terminology rebased, now absorption is no longer referred to as health and health/absorption together are called hearts.
- The health regen disabling option now sets the game rule's default value rather than constantly setting it
- Food healing rebalanced
   - Only counts actual hunger and saturation restored, rather than counting total value of food eaten
   - Now counts saturation (on its own drumstick:health ratio)
- Armor replacement rebalanced
  - Most settings can now be enabled/disabled independently (still need to be enabled by master toggle)
   - Now armor and armor toughness can each provide absorption hearts and/or absorption recovery rate
