read_plus.zsh: Various Updates
* Clean up colors/read_plus.py to match flake8 style guidelines * Add --dmesg, --srvdmesg, and --no-server-vmtouch options * Use $COLORS from common.zsh * Accept a specific filename to test as a command line argument * Add tests for 3, 5, 6, and 7 page segments Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
