Xenocontendi Revived 16x

Finally added 1.21.4 support, along with general fixes and additions to the pack

• Added pale garden blocks:
  • Pale oak log
  • Pale oak planks
  • Full Pale oak wood set
  • Creaking heart block
  • Eyeblossom
  • Pale moss blocks and items
• Changed pack ver to #46
• added air_empty addition

Minor fixes/changes:

• Fixed several file name changes with 1.21.2+
  • Armor textures
  • Empty Armor slots
• Fixed endermen textures compat with EMF
• Added Warden texture to match with rest of pack

Note: The Creaking mob is NOT textured but I will probably eventually get to making my own, but the vanilla texture looks fine for the time being
