Spottedleaf 4b0bc74c90 Initialise default nibble arrays in ChunkAccess directly
When ChunkAccess was converted to an abstract class some versions
ago, the code to initialise nibble arrays should have been moved.
However, the code was not moved and so now mods constructing their
own implementations of ChunkAccess would not have the nibble arrays
initialised.

This is ported to Paper from Starlight to keep the code base in sync,
not because it fixes anything known.
