Update to MC 1.20.6

- Update EMI and REI integration, and fix some issues with the upgrade
   crafting hooks.
 - Just use smooth stone for recipes, not #c:stone. We're mirroring
   redstone's crafting recipes here.
 - Some cleanup to printouts.
 - Remote upgrade data generators - these can be replaced with the
   standard registry data generators.
 - Remove the API's PlatformHelper - we no longer have any
   platform-specific code in the API.
