Add support for animated gif/webp/apng images

### Problem description

The animated image is a very popular image format, which can currently not be displayed by tabris natively. An existing workaround is to use a `WebView` but that is more resource intesive than it has to be.

### Expected behavior

Support displaying animated images with the ability to start/stop/pause the animation and to receive load/progress callbacks.

### Environment

- Tabris.js version: 3.0
