minimodem: --stopbits replaces --txstopbits; better bps metric
...
RX metrics account for fractional number of stop bits (e.g 1.5);
RX bps metric slightly more accurate (?).

fsk_find_frame() takes expect_bits_string (e.g. "10dddddddd1"), as a
parameter supplied by the caller allowing for encodings which don't use
any start/stop bits (e.g. just "dddddddd").
