Leah Rowe 2bb17c61d0 spkmodem-decode: learn tone per frame, not sample ...

the fir filter produces stable frequencies per frame,
but learning per sample (within a frame) means we
record the same value roughly 240 times.

here, we are syncing up at just the right moment
instead, and only at that moment, this increasing
both performance and reliability.
