Add Pulse DTR command

Browse source 
MCUs like the ESP32 can be reset if the serial port DTR line is
pulsed for a short time.  You could just type CTRL-t d CTRL-t d
but that's a little awkward since you have to lift your finger
off the CTRL key to type the Ds.  Now you can just type CTRL-T D.

* Added new command "D" to pulse the DTR line.  I.E.  Toggle its
  state twice with a configurable duration between toggles.

* Added new config/command line option "--dtr-pulse-duration"
  to set the duration between the DTR state toggles.  The default
  is 100ms.
