BMNW neoforge 0.4.0 for 1.21.1!

This update does not add many blocks, but it does add important systems.

• Added the PipeNet system, for transporting fluids quickly
• Added the CableNet system, for transporting RF quickly
• Added the Fluid Identifier with a selection screen
• Added fluid barrel and energy storage block
• Added volcano cores (hbm reference)
• Added combustion engine
• Revised nuclear waste barrel texture
• Item fluid containers with extremely hot fluids inside will now be extremely hot themself
• Every recipe has been JSON-ified, which means data packs can modify recipes
• Added Builder's Furnace (used for quickly smelting building blocks because furnaces are soooo slow)

nukes will probably return in 0.5.0 i think
