Investigate compression methods.

[JodiTheTigger]

Write a program that takes a working game state recording, and tried all the different knobs on compression to see which one is better for that game type.

Make it easy to use, as it will be a tuning tool for setting compression parameters in the delta coder.

Things to test so far:

-Xor delta with base or not
-Encode the value zero as a special value (1 bit if zero, +1 bit if it isn't)

[JodiTheTigger]

Another group to test:

zlib:
No delta: just zlib the (target) state.
delta: create delta bitstream, zlib
delta: xor base and target (no delta bitstream), zlib resulting buffer

A Search for "delta encoding zlib" compression give a few leads as well.

Depends on Issue #50 been done, doesn't need to block any milestone at the moment.
