A fix for MC-159109 (Java)

As of Minecraft Java edition 1.14, due to MC-159109, redstone no longer loads chunks. To fix this, when a redstone update is detected, a 3 by 3 area of chunks centered on the chunk where the redstone update happened will be loaded at level 32. Chunks loaded via this method will unload after 15 seconds, unless another redstone update is detected. If another redstone update is detected, it will load the chunks at level 32 for another 15 seconds. The 3 by 3 area of loaded chunks will allow redstone updates to progress to the next chunk without being affected by the bug.
