Regarding 1.21

- PacketPlayInBlockPlace contains yRot and xRot
- Heavy changes to PlayerChunk, PlayerChunkMap again,
- TicketType LIGHT removed

- ARMOR -> HUMANOID_ARMOR
- Remove Itemstack "trap" code?. Test foxes again for NPE
- Check how badly findPlayerWithOminousEffect is implemented

Hotswapping laggyness
- Increasing these does not help WEBBIGBOISNOW='-XX:+SegmentedCodeCache -XX:NonProfiledCodeHeapSize=32m -XX:ProfiledCodeHeapSize=128m -XX:NonNMethodCodeHeapSize=64m -XX:ReservedCodeCacheSize=224m'
- A lot of classes are loaded multiple times by multiple classloaders? Is this normal for hotswapping?
- Bug seems to be from either:
  - Java 21 in general
  - JBR JDK 21
  - Hotswapagent
  - G1GC?
  - (MC changes?)
- Fixing hotswapping laggyness in Java 21:
  - Call System.gc() on a detected change as the simplest hotfix
  - Force enable UseCodeCacheFlushing, MethodFlushing, NmethodSweepActivity
  - StartAggressiveSweepingAt, SweeperThreshold
