Cache wavesurfer data

[ImExoOdeex]

I have a default song library component that has few static songs, everytime user changes the render of this component they get lagged, due to all the wavesurfers loading all over again, it would be cool to save/load wavesurfer data into custom storage like localstorage with some custom keys, like url, width and height, eg. ws-{song.url}-{width}-{height}.

Good idea. Feel free to propose a PR.

You can also do it in your app like this:
