Sort NBT data where applicable

[uncovery]

We might need to sort enchantment arrays to make sure 2 identical enchanted items can stack.
Most likely this is only needed when we store the item in the database.
We cannot sort everything since banner sequence changes the look.
Things to sort:

• enchantments
• potions?
• fireworks?

[uncovery]

Enchantments are done.

[uncovery]

Potions (as the default potions) don't need to be sorted since they have only one effect

[uncovery]

Need to double-check if fireworks sorting makes a difference.
