Add regular hearts to the game and make them obtainable through butchery

Summary

Content "Add regular hearts to the game and make them obtainable through butchery"

Purpose of change

For some reason, there is yet to be regular, non-jabberwocky hearts in game
I decided to add them

Describe the solution

• Add the hearts food items
• Add the snippets for mutant hearts
• Add recipes using hearts
• Add hearts to recipes using organ meat
• Make the hearts be harvestable from humans, demihumans, mutants and non-insects animals

Describe alternatives you've considered

Let almost every living being be literally heartless

Testing

Game loads without errors, animals can be butchered and will drop chunks of heart
Butchering the others also drop hearts

Additional context

Not giving hearts to black dragons yet. They are dragons, so their hearts are expected to be special like the rest of their butcher products, but making special hearts is above the scope of this PR

• A chunk of heart from a mutated animal. Patches of hair and bits of bones are present all over and inside it, making it resemble a giant teratoma. Despite this, it appears to have functioned as a heart.
• A chunk of heart from a mutated animal. This cancerous, gangrenous mass of flesh still beats, leaking out more of the foul fluids it used to push through a body. Beating isn't the only thing it continues to do, as you witness what kept this heart beating: the gangrene eating the cancer as the cancer grows back all over the gangrene, in a sickening ouroboros.

Hints for adding a new word to the dictionary

• If the word is normally in all lowercase, such as the noun word or the verb does, add it in its lower-case form; if the word is a proper noun, such as the surname George, add it in its initial-caps form; if the word is an acronym or has special letter case, such as the acronym CDDA or the unit mW, add it by preserving the case of all the letters. A word in the dictionary will also match its initial-caps form (if the word is in all lowercase) and all-uppercase form, so a word should be added to the dictionary in its normal letter case even if used in a different letter case in a sentence.
• For a word to be added to the dictionary, it should either be a real, properly-spelled modern American English word, a foreign loan word (including romanized foreign names), or a foreign or made-up word that is used consistently and commonly enough in the game. Intentional misspelling (including eye dialect) of a word should not be added unless it has become a common terminology in the game, because while someone may have a legitimate use for it, another person may spell it that way accidentally.
