Add zoom effect (Kim Burns effect) to image

The [Kim Burns effect](https://en.wikipedia.org/wiki/Ken_Burns_effect#:~:text=The%20Ken%20Burns%20effect%20is,video%20production%20from%20still%20imagery.&text=The%20feature%20enables%20a%20widely,and%20fading%20transitions%20between%20frames.) is the zooming on a image. It turns your image into a small video. There are sufficient tools to do this, but it would be an enrichment to have it built-in into yodeck. thx Johan
