Adding paper-attaching to wrapped packages (#47329)

About The Pull Request

This lets people attach paper to wrapped packages that can be read on the package and comes off when the package is ripped open. This works almost exactly like airlocks. This is my first time spriting so feel free to criticize.

Why It's Good For The Game

Makes the mail service system more useful by allowing information about packages to be directly attached to those packages.
