WIP: Planktons and Plankton Coop (Patreon)

The Plankton Coop will be a place to generate various kinds of pantry items from, and can be built in edge slots much as the puffer docks can be. For now it'll be as simple as finding a wild young plankton and putting them inside of the coop and harvesting them periodically, but we might make a more complex mechanic in time that lets you store multiple kinds of plankton, but with various kinds not liking one another.
