Armor Stand Optimization For servers

## ArmorStandOptimizer 1.0.0 - first release

Armor stands that are doing nothing stop ticking, and wake the moment anything
happens to them. Nothing about how they look, behave or get hit changes.

### What's in it
- Idle armor stands rest instead of recomputing physics twenty times a second
- They wake instantly on damage, punches, pistons, flowing water, explosions, a
  block breaking underneath them, teleports, or another plugin moving them
- Optional per-player render budget for huge piles, with anything held back kept
  fully clickable
- Invisible stands with no hitbox are never sent to clients at all
- /aso status shows how many are resting and why the rest are not
- Four presets: balanced, safe, max, off

### Measured
5000 armor stands piled in one spot, on Paper 1.21.11:
- without the plugin: 13.1 ms per tick
- with the plugin: 3.7 ms per tick

72% less tick time, with every stand still falling, burning, breaking and
teleporting exactly as it did before.

### Requires
Paper 1.21.11 through 26.2. Spigot and CraftBukkit are not supported. Folia is
not supported.
