Open Ended Pipe Effect Handlers

Effect handlers for open-ended pipes can be registered to allow for custom behavior when such a pipe is spilling fluid.

• Implement OpenEndedPipe$IEffectHandler
  • canApplyEffects checks if effects should be applied for the given FluidStack
  • applyEffects runs when effects should be applied
  • Both methods receive the OpenEndedPipe instance as context to allow getting the world, position, etc.
• Register an instance with OpenEndedPipe#registerEffectHandler
