Book Binders store lvl as Int

[Bloo-dev]

Describe the bug
When binding a book from pages in a book binder, the resulting enchanted book will have its enchantment lvl fields stored as int. Whilst this is supported by most parts of minecraft, modules that test specifically for lvl:<something>s will fail to detect this as they are expecting a short.
One module affected by this is Zauber, Crystals can't be crafted using these Book Binder books. As lvl should be a short by default, Book Binders should be adapted. However, the Book Binders module never actually specifies to store as an integer and the conversion is done by the game when copying the enchantments into storage.

To Reproduce
Steps to reproduce the behavior:

1. Craft an Enchanted Book from Pages
2. Inspect the NBT before placing the Book in a container

Expected behavior
lvl should be a short

Fix
I really don't know.

Workaround
Placing the enchanted book in a container will update the lvl tags to be shorts.

Environment

• Minecraft version: 1.15.2
• Server version: 1.15.2, Paper (git-Paper-371), Public Server 6

I haven't looked at the code, but if it only exists for a tick you can copy it to storage or something

This might be fixed in 1.17.1.

This no longer occurs in 1.17.
