Fix smoothTime set to 0 not work

[Ami-OS]

In this line:

options.smoothTime = Number(options.smoothTime) || wZoomDefaultOptions.smoothTime;

https://github.com/worka/vanilla-js-wheel-zoom/blob/727db6934e4d84d562c87a5e44bb66fccca7f894/src/wheel-zoom.js#L372C60-L372C60

Has something problem, since smoothTime option value can set to be 0, but the || operator means check "falsely" (false == 0), so if we set that the 0, || operator will assume that the value is false lead to be apply default value.

So I think we could use ?? operator, who will check undefined or null instead of the "falsely".

Fix:

options.smoothTime = Number(options.smoothTime) ?? wZoomDefaultOptions.smoothTime;
