AppliedE

Initial port to MC 21.1.

• Overhauled textures to bring them up to date with current AE2 (courtesy of @Ridanisaurus)
• Reworked most item and recipe type mappings: recipe types are now all mapped by a single mapper, while condenser outputs have been moved to the defaults.json custom conversions file
• Reworked most internal Mixin logic to not be as intrusive/destructive in case other add-ons decide to take similar approaches to reporting additional information for terminal entries
• EMC tiers are no longer reported as "craftable" on terminals (though patterns are still present internally as normal for EMC autocrafting purposes)
