PPeTP

• Fixes critical issue where nautili are erroneously teleported (#5)

• Update to 1.21.11

• Fixes an npe with pets without owners (#2)
• Fixes a potential npe in weird situations
• Adds defensive try-catch blocks to make the mod behave well in miscellaneous cases

• Fixes a left-over debug statement
• Formalizes behaviour for pets teleporting across dimensions
  • By default, PPeTP will use the vanilla behaviour of not teleporting pets across dimensions. Pets will still be prevented from being lost, but won't teleport until you're back in the dimension the pet originates from
  • You can change this behaviour using the petTeleportCrossDimension game rule

Adds support for DFU. This means that if Mojang decides to change what entities look like in a future version, your pets will be properly updated as well.
