Staff Mod 0.1.1-alpha.2

0.1.1-alpha wasn't released, because the CI didn't work as I thought

What's new since 0.1.0

• A bunch of code under the hood, so I can add some content in 0.1.2-beta next week. Stay tuned
• You can now find staff in the creative inventory

What changed since 0.1.0

• Update staff model and texture
• ⚠️BREAKING CHANGE⚠️
  • Staff item NBT changed - item previously added to the staff will be inaccessible
• Staff now drops its item when destroyed
