Option for uncontrolled zoom

[clinton-encord]

Hi!

Wavesurfer's zoom method automatically does some scrolling to ensure cursor stays in the center.

Could we add a setting to disable that automatic scrolling?

i.e.

/** Zoom the waveform by a given pixels-per-second factor */
public zoom(minPxPerSec: number, autoCenter = true) {
...
}

Actually it seems like I can just override the scroll by using wavesurfer.setScroll().
