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.
Streamlined the queue so now the queue doesn't need to be fetched on
each block
Removed block reording from editsession as it alone takes half a
second/million blocks
Replaced block fetch from history extent with optimized algorithm.
