Fixed pre-1.17 server players not being registered as in creative
Re-enabled the setting packets to null optimization
Fixed the delay when entering non-living non-boat vehicles

Update PacketEvents to fix:
- WrappedBlockState was setting the block cache to air after updating a block. This broke block placing and opening doors/trapdoors on 1.13+. This fixes more than you would think and caused major issues with block placing and interaction.
- Netherite pickaxes were not tracked correctly leading to ghost blocks appearing to grim.
