clique: simulate diff_inturn and diff_noturn chains, goerli/eips-poa#13

deps

requires ruby 2.6 and the colorize gem: gem install colorize

run 1 simulation

run 1 chain simulation with diff_inturn=2, diff_noturn=1, peer_count=8, and net_fragmentation=0.001

ruby ./diff.rb 2 1 8 0.001 true

the last argument true enables debug logging to display the actual chain simulation:
