atrf-txrx: added BER test pattern transmit mode

- atrf-txrx.c (main): indicate mode of operation in variable "mode" instead
  of dual-using "cont_tx"
- atrf-txrx.c (usage, main): added option -B to enter BER test pattern
  transit mode
- atrf-txrx.c (transmit_pattern): transmit raw frames with a cyclic frame
  number
