libatrf: add option to send a pulse with atrf_slp_tr

- include/atrf.h (atrf_slp_tr), lib/atrf.c (atrf_slp_tr): added pulse
  argument
- atrf-proxy/PROTOCOL, atrf-proxy/atrf-proxy.c (cmd_two, cmd_more):
  added second argument to SLP_TR command
- atrf-xtal/atben.c (atben_sample), lib/cwtest.c (cw_test_end): updated
  for API change
- lib/driver.h (struct atrf_driver): added "pulse" argument to slp_tr
- lib/atben.c (atben_slp_tr), lib/atnet.c (atnet_slp_tr): added support
  for pulse mode
