Primordial Soups

Initial beta version of the mod.

Adds two blocks, the Primordial Crock and the Stock Deposit.

Adds the crock_camp structure that spawns in #forge:is_plains biomes and contains a Primordial Crock.

Adds the stock_deposit_ring structure that spawns in #forge:is_sandy biomes and contains a Stock Deposit.

Adds iron soup fluid (currently unobtainable in survival), which dries up into iron ore when it receives a random tick.

Adds stock fluid (might be obtainable using a mod to extract stock from the deposit), which can be placed in the world but does nothing special.

Adds iron soup bucket and stock bucket.
