BetterEnd Crashed Ships Tweaks

BetterEnd dynamically generates crashed ships around the end, but despite generating brewing stands with potions and a dragon head, the chests generate completely empty!

Apparently, there are no plans by BetterEnd to change this, so I decided to release this patch (for a modpack, but anyone can use it). The mod is currently just a simple mixin which automatically adds loot to every newly generated crashed ship. It should also work with any datapacks that modify the ship nbt, such as IchPhilip's Better End Cities.

THIS WILL NOT ADD LOOT TO SHIPS THAT HAVE ALREADY BEEN GENERATED

Planned - Configurable values for:

• Spawn rate of crashed ships
• Chance to enable spawned hostile entities in the ships
• Discard chance for chests/elytra
