MobStacker 1.12.3 for Minecraft 1.16

• Fixed an issue with entity breed timers causing improper re-merges
• Stacks are now damaged appropriately by piercing arrows
• Supports bees (guess I forgot to make a release for 1.15, whoops) and other new mobs
• Requires 1.16

MobStacker 1.12.1

• Fix oversight when attempting to transfer leash ownership

MobStacker 1.12 for 1.14+

• Changed MobStacker to use the new 1.14 PersistentDataStore API.
  • For now, this offers backwards compatibility for the old system in which stacks were defined by name. Eventually this will be removed to greatly improve performance.
  • This resulted in a config change: load-existing-stacks is now a boolean, not a container for a boolean and a list of entity types. Stacks either persist or do not, there is no middle ground for various entity types.
• Loot will make a "best attempt" at generating, however, due to some 1.14 changes MS cannot guarantee that loot will successfully generate. Please open a new issue if you see any errors in your console - MS will gracefully fail, but it would be great to actually fix the problem.
• Dropped items will now merge into stacks before dropping, which should vastly improve client performance.

Apparently this is the first release I've made of my MS fork, so if you're after the rest of the changes, please check out the commit history.
