A simple datapack that adds the dependence of player characteristics on hunger level.
(attack_speed, attack_damage, movement_speed in 1.20 and earlier versions, on 1.21 i`ll add more)


At hunger level 20+, the player's characteristics are the same as in the normal game.
At hunger levels below 20, the characteristics slowly decrease until at level 0 they become 2.5, 0.67 and 0.025.
