Modular Forcefields (MFFS) 1.21.1-0.6.0

New features

• Sponge module now works — The sponge module no longer just sits there as a placeholder. It now actually removes fluids from blocks inside the field.
• Biometric identification for the field projector — The field projector can now use a Biometric Identifier to let specific players pass through the field while blocking others.
• Rendered fortron rays — The fortron beams/rays now render properly.
• Colourless fortron fluid texture — Added a texture for colourless fortron fluid.
• Updated JEI and Neoforge — The mod now uses newer versions of the JEI (Just Enough Items) and Neoforge libraries, keeping things compatible with the latest setup.

Fixes

• Fixed Interdiction Matrix permissions, protection, and inventory transfers — The Interdiction Matrix now handles permissions, protection, and moving items in/out correctly.
• Beams now use default Minecraft settings — Added a config option so the fortron beams can be based on your default Minecraft settings.
• Reverted fortron field colour when modules are absent — The field colour is now reverted when modules are missing.
• Removed deprecated code — Old, deprecated code has been stripped out across the mod.

Note: A large earlier commit ("Preliminary move to null-analysis-based system") introduced MFFS' null-analysis system and bumped the version to 0.6.0. It's the foundation for the changes above and doesn't need separate explanation for daily use.
