[DTPK] 1.1.1 | Backpacks! 1.21-1.21.1

Made some changes regarding to how to backpacks (chest minecarts) tps because Mojang doesn't like item displays.

(1.1.1):
- Fixed:
  - You couldn't open the backpack when facing down.
  - Sometimes the backpack (chest minecart) wouldn't even tp at all (I needed to remove the tp accuracy to fix this, srry).
  - Now it resets correctly when rejoining on a singleplayer world.
