Leah Rowe 78b71f867f util/spkmodem-decode: automatic tone calibration ...

current logic is hardcoded, as in the original spkmodem-recv.

with this change, small differences are observed and averaged,
then the detection thresholds are adjusted accordingly.

the existing macros serve as a baseline, but real signals
differ. with this change, we therefore account for possible
drift in timings, which can change in real-time; the old
code could possibly get out of sync beccause of that, which
may have resulted in corrupt characters on the screen. this
change therefore should make the output a bit more stable.

the detection window is continually adjusted, so that the
output timings don't drift.

the tolerances are automatically adjusted based on base
timings (see new define in patch)
