I plan to mark some fields as IP address and print them respectively. The --format hex is not nice switch for this and introducing one more (--format hex ipadd) is too bad. So let's fix the cirt API to be simple and stupid. By default crit generates canonical one-line JSON. With --pretty option it splits the output into lines, adds indentation and prints hex as hex and IP as IP.
