--[[ Data value format notes:
Hunger values is identical to Minecraft's and ranges from 0 to 20.
Exhaustion and saturation values are stored as integers, unlike in Minecraft.
Exhaustion is Minecraft exhaustion times 1000 and ranges from 0 to 4000.
Saturation is Minecraft exhaustion times 10 and ranges from 0 to 200.
Food saturation is stored in the custom item definition field _mcl_saturation.
This field uses the original Minecraft value.
