Add timeout based timestamps in hex output mode

Browse source 
This change reintroduces timestamping in hex output mode but based on
timeout instead of new lines which made no sense. This means that
timestamps will only be printed when timeout time has elapsed with no
output activity from serial device.

Adds option --timestamp-timeout <ms> for setting the timeout value in
milliseconds.

Defaults to 200 ms.
