Community Fluid API

Initial release/"fork" from the greater Functional Fluids mod. Alpha might be a better designation, but I want to make sure this is visible through the Modrinth maven as a dependency for Functional Fluids.

This file contains all of the mixins required by any mod that wants to implement modded fluids, so they can be used independently of the Functional Fluids example mod. For minor technical reasons, it has not been fully tested as a standalone mod.
