Forge 1.20.1 backport — full port from NeoForge 1.21.1 to Forge 1.20.1 (Java 17, Forge 47.3.0).

• Pipe Terminal — access all inventories connected to the pipe network from a single block. Supports searching, extracting, inserting, and crafting directly from network resources. Place next to any item pipe to connect.
• Tiered Barrels — Oak (27 slots), Copper (45), Iron (54), Gold (72), Diamond (90), Netherite (108, blast resistant). Upgradeable in-place with barrel upgrades that preserve contents.
• Waterlogged pipes — all pipes can now be placed underwater. Water flows correctly around pipe geometry.
• JEI descriptions for all items — barrels, barrel upgrades, Void Attachment, Sensor Attachment, and Terminal now have info pages in JEI.
