minimodem: --rx callerid
...
New "callerid" baudmode supports Bell202 Caller-ID (MDMF or SDMF) prototol.

minimodem: --rx prints all bytes unmolested, unless --print-filter
...
Now, minimodem prints all received bytes without isprint() filtering,
unless --print-filter is specified. Allows for binary file transfers
and multibyte characters.

minimodem: performance: read samples in larger blocks
...
For performance, read samples from the simpleaudio backend in larger
blocks when the number of bits per frame ends up being small.

simpleaudio-pulse: fix intermittent --tx noise

For some unknown reason setting attr.prebuf=1 causes horrible noise
for some playback sessions, so don't do that.

simpleaudio-sndfile: fix minimodem tx_interactive
...
Un-break tx_interactive: minimodem enables tx_interactive whenever the
stream_name is NULL, so go back to using the stream_name as the sndfile
filename.

minimodem: refine fsk frame position on carrier acquisition
...
FSK_ANALYZE_NSTEPS was previously 10.
Now FSK_ANALYZE_NSTEPS_CARRIER_LOCK is 100, and FSK_ANALYZE_NSTEPS is
reduced to 4.
(Also, try_confidence_search_limit = INFINITY on carrier acquisition frame).
Effects: Better initial phase lock on signal in the first
place; sloppier tracking of fast/slow signals; reduced longterm CPU load.

RX metrics account for fractional number of stop bits (e.g 1.5);
RX bps metric slightly more accurate (?).
