Target number of points when producing JSON?

[tremby]

Is there a way to ask audiowaveform to produce roughly n points, when producing JSON? It doesn't need to be exact.

I know I can do this with a simple calculation ahead of time involving the duration, and passing a suitable value in to --pixels-per-second, but I'm wondering if there's either something obvious I'm missing or if it's a feature which could be added. It's a shame to need to use a separate tool to find the duration of the audio, when audiowaveform is calculating that itself anyway.

Thanks for raising this. At it's essentially a duplicate of #114, I'll close this and follow up in that issue.
