libatrf: cw test mode can now be resumed, with lower overhead (231 only)

Browse Source 
- lib/cwtest.c (enter_test_mode_231, prepare_test_mode_231,
  start_test_mode_231, cw_test_begin): broke enter_test_mode_231 into
  a slow setup component and a fast start/resume component
- include/cwtest.h (cw_test_resume), lib/cwtest.c (cw_test_resume):
  resume transmission in a previously set up test mode
