Schematics now load in a fraction of a time. (took me 5.13 seconds to
load a 102,572,228 block schematic)
Also made some minor optimizations here and there.
Using java's inbuilt compression algorithms (gzip or deflator both) was
a bit too slow for me.
Fawe is now using the LZ4 compression algorithm, which is super fast. So
fast that I decided to add a default 1 pass of compression to history.
Enabling further compression will do an additional high LZ4 compression.
