Aikar c95273f973 Optimize Chunk Saving Memory Allocation and Compression
Minecraft ineffeciently uses OutputStreams by calling .write(int) on the stream.
For Chunks, this is a DeflaterOutputStream, which allocates a single byte EVERY write.

This is causing the server to allocate tons of new byte[1] objects.
Additionally, this is very ineffecient for the Deflate process.

By Buffering Writes the same way it already is Buffering Reads, we will
write to the stream much more effeciently.

Also a more effecient RegionFile zero'ing for new chunks to speed up
new chunk generation.
