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.
