Fixes

• Fixed crash when loading in a server environment.
• Optimized math operations to use less object allocations.
• Optimized predicate ordering.
• Updated glare detection logic. Skeleton stare timer goes down regardless if it's out of range, blocked by blocks, etc. Either way, this makes more sense.
• Reduced the amount of NBT writes.

Doing some playtesting, my implementation of this mixin into the player is much, much worse on TPS than having 300+ skeletons around in a singplayer world. Go figure.
