Zombie Awareness Freeze Fix

Got Zombie Awareness installed?  Have you ever run into an issue with the End Ship, or other mods that add item frames to their structures, where the world will freeze?

Turns out there's an unpatched flaw in Zombie Awareness that causes this.  This mod uses mixins to patch that issue.  Until Corosus finally decides to patch it, use this mod as a hotfix

Currently this mod is only ported to 1.16.5, though theoretically it could be ported to any version with the issue without much trouble.

Modpackers who have fixed the issue using datapacks can now be redirected to this mod instead.  Third-party launchers have full distribution access.

Here is some evidence of the mod working as intended.  Usually during failure you cannot even teleport to this structure, or even see the advancement pop, and the server would freeze, but here it works as normal:

TelepathicGrunt is fully credited for the mixin part of this mod.  Any future ports would be performed by Kaleidio.
