[Suggestion] When using Lava Boilers, support Lava Bucket stacks

[BritishCynic]

Expected Behavior

The Lava Boiler, like the Coal Boilers, correctly supports stacks of Water Buckets, however it does not support stacks of Lava buckets.

Current Behavior

If I put a stack of Lava buckets in the Fuel recepticle, it consumes the entire stack and replaces it with a single empty bucket, presumably because it has nowhere to keep separate stacks of Lava buckets and empty buckets.

Possible Solution

Modify the UI to include a separate slot where empty buckets can be sent, and ensure that when a lava bucket is consumed, only 1 bucket in a stack is consumed.

Steps to Reproduce (for bugs)

Use Lava Boiler. Add water. Put in stack of Lava buckets. Watch as it consumes entire stack.

Context

It makes the Lava Boiler a less attractive option than the Coal boiler.
