Clumsily cut-n-paste interpolation into pitch tracker as well

Add rather simplistic cubic interpolation for peak values in a cepstrum output (not yet for pitch tracker). Only gains us 1dp

Introduce peak-to-second-peak ratio, which looks like a reasonable proxy for harmonic-ness. Use it to ascribe a confidence to estimates in the pitch tracker & rely on that to determine how many similar estimates make a satisfied hypothesis

Reap expired/rejected hypotheses from list; report an estimate as accepted only if the accepting hypothesis has been satisfied already (otherwise a different provisional hypothesis might become satisfied first)

Change "relative to mean" to "relative to RMS", and add peak-to-RMS output. Add a mean-filter history. Remove essentially useless forward-power method (same as forward-magnitude with 2x factor). Refactor a bit
