Rite of Returning 1.2.2

Soul Spear unmodified model hand fix:
- The uploaded Soul Spear.bbmodel is now copied byte-for-byte into the mod.
- The model file is not normalized, converted, reshaped, or rewritten.
- Held item uses:
  assets/riteofreturning/models/item/soul_spear.bbmodel
- Projectile uses:
  assets/riteofreturning/models/entity/soul_spear_projectile.bbmodel
- Removed extra custom renderer first-person/third-person transforms that pushed the spear behind the player.
- Item JSON uses the uploaded model's own display values.
- Renderer only centers/scales the original Blockbench model into item-render space.
- Direct look-vector throw retained.
