Mediaplayer service

It would be great to support native APIs of the operating systems. For Mac, there was good work done by the @captbaritone in the #10. Later, we can look at https://www.npmjs.com/package/electron-media-service and try to port it to N-API.

For Linux, we can use https://www.npmjs.com/package/mpris-service.

For Windows, https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/system-media-transport-controls is the way to go. We can hopefully use automatically generated NodeRT module.
