Wall-clock length in milliseconds of the echo tail a point produces: the
onset of its final echo, plus that echo's own tone and its reverb decay.
Mirrors the scheduling in scheduleEchoes and playOscillator.
Exported so the arithmetic autoplay paces itself by can be tested without
standing up an AudioContext.
Parameters
numEchoes: number
Echoes actually scheduled for the point
maxEchoCount: number
Configured maximum, which sets the reverb ramp
echoDurationSeconds: number
Delay between consecutive echoes
Returns number
Tail length in milliseconds; 0 when no echoes are scheduled
