Oritech Extensions

First release for Fabric (Minecraft 1.21.1). Needs Oritech 1.2.x for Fabric, Fabric API, Architectury API, Forge Config API Port and GeckoLib (Oritech needs all of them too). Quilt isn't tested.

Same features as the NeoForge version:

• Industrial Hangar Door Extensions (up to 16 blocks by default, configurable).
• Color Cartridges paint machine addons and extenders, item and fluid pipe networks (with colour-isolated pipes), Industrial Glass, whole nuclear reactors and whole particle accelerators.
• Paintable block tags for modpacks (oritech_extensions:paintable and oritech_extensions:paintable_connected).
• The Oritech Extensions Guide, with the in-game wiki through Oracle Index.

Not on Fabric:

• Oritech Things addon painting, because Oritech Things has no Fabric build.
• An in-game config screen. Edit config/oritech_extensions-common.toml instead; the options are the same as on NeoForge.
