Polar world format for Paper 1.21.10

Warning

Not widely tested, possibly unstable. Backup your worlds before if you don't want to lose them!

What's changed

(benchmark figures are from very limited testing on a small world, but it's definitely faster!)

  • Fixed command permission nodes
  • Fixed autosave timer not stopping on config reload
  • Fixed rare entity save error
  • Significantly faster loading (~3x faster)
  • Significantly faster saving/converting (~14x faster for individual chunk)
    • Fully skip blank chunks (previously had to load the chunk to find out it was blank)
    • Skip already saved chunks (meaning repeated saves are even faster)
  • Removed source and allowWorldExpansion from config
  • Removed centered option from /polar convert
  • Removed chunkradius from /polar save
  • Split blockPhysics gamerule into blockPhysics and blockGravity
  • Added time option to config
  • Added async option to config (very experimental and likely to cause issues)
