feat: automate editing appearances.dat

[luan]

Sometimes all you want is make that one item house-wrappable. Or add use-with to something. But you don't want to have to load up asset editor since it's heavy and has a lot more features. You can use client-editor to edit appearances.dat directly.

# Windows
.\client-editor.exe appearances -a appearances.dat -c config.toml

# Unix
./client-editor appearances -a appearances.dat -c config.toml

It'll write a appearances.out.dat file with the changes. You can then copy that over to your client and to the canary data/items/ folder to have your changes applied.
