Add documentation of WHY developers should use this instead of HtmlAudioElement

I cannot find in the readme anywhere an explanation of what advtantages and differences this plugin brings to using the HTMLAudioElement

See this post, also looking for such more details:

In my opinion the usage-case/reason of a plugin should be very visible in the documentation.

Thanks a lot for the plugin. If you quickly mention the pros/cons of each, I could make a PR for documentation and elaborate more
