Added -s, --stat option to print statistics
Print, for each stream, time delta from SSL/TLS handshake and each SYN_STREAM. The time deltas are measured after SYN_REPLY received and all data received. For example, the following output: SYN_REPLY: X(Y) means SYN_REPLY was received X ms after SSL/TLS handshake and Y ms after the corresponding SYN_STREAM was sent.
