Create: Occult Engineering

This release is nearly a like for like port of v1.20.1-0.9.0 to 1.21.1 with a couple fixes and changes:

• Phlogiston has been made cheaper, and no longer requires Afrit Essence.
• The Otherworld Detector now works properly on the server.
• A NBT tag has been added to the player when they can see into the otherworld occultengineering:third_eye_active.
• Phlogiports now push and pull from the inventory below, much like Frogports, making them a 1 for 1 replacement.
• The Mechanical Pulverizer will only process items if it has the inventory space. Everything has now been tested on a dedicated server, so there should be less bugs in multiplayer.
