Beyond The End - Optimization and Fixes

    Nature's Compass searches biomes on the server thread through Forge's
    WorldWorkerManager, which gives the search the spare time of every tick
    and at least 10 ms, so the server loses >= 10 ms per tick while a compass
    is searching and the search only goes as fast as the spare tick time.
    With the modpack config (radiusModifier 25000, maxSamples 1000000) a
    search for a biome that is not nearby can run for a very long time.

    - AsyncBiomeSearch: walks exactly the same spiral as BiomeSearchWorker
      (same steps, radius and sample limits, same heights) on its own thread
      and checks the columns in parallel batches of 256, keeping the first
      column in spiral order that has the biome, so the position and sample
      count are the ones the original would report.
    - BiomeSearchWorkerAsyncMixin: doWork() starts the search, keeps updating
      the search radius shown by the compass every 500 blocks and, when done,
      calls the original succeed()/fail(); it returns false meanwhile so the
      worker manager does not spend tick time on it. stop() cancels it.
    - A biome the dimension cannot generate (not in its BiomeSource's
      possible biomes, e.g. a Twilight Forest biome searched in the
      Overworld) now fails at once instead of walking the whole spiral.
    - Nature's Compass 1.19.2-1.10.0 added as compileOnly from libs/
