Matcha-flavored-style hunger

Primarily just takes the hunger mechanic from Matcha Flavoured. The goal of this datapack is to use that feature without relying on other mechanics or a resource pack. Majority of the code and credit belongs to Klei, creator of that datapack.

Given that some foods don't exist in vanilla that exist in Matcha Flavoured, some were added. Many foods from Matcha Flavoured do not exist. Loot tables were not adjusted to have food that heals the player. To compensate, most foods can be placed into the crafting table to turn them into their healing variant. Beetroot and melons are an exception, since those have pre-existing recipes.
