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.

With and without timestamp support for each broken up line.
* Add support for activity based time stamping in both normal and hex-mode.
* Add support for activity based time stamping in normal output mode
Will print a new timestamp if there is no input activity within the time
defined in the configuration file, e.g.:
Already supported in hex output mode.
timestamp-timeout = 200
Time is in ms.
* Advanced line mode
* Advanced line mode
Current line mode only support backspace editing. Would be nice with arrow
key navigation left/right and insert/overwrite support. Also history browsing
