minimodem: restrict try_max_nsamples to 75% of a bit-width
...
... actually 125% of a bit width before acquiring carrier.

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").

Significant performance enhancements from fsk_confidence_search_limit:
runs far fewer FFT's when --limit (default 2.3) is less than INFINITY.

Computes SNR confidence value, where "signal" is the magnitude of the FSK
driven frequency, and "noise" is the magnitude of the non-driven frequency.
(Also includes unused algo #4 code, which may not compile anymore.)
