Gif decoding is done on UI thread

The decoding of the gif file is done on the UI thread. it cause a freeze of the application when loading large gif.

The performance of this package is indeed quite slow, don't overuse it or you might freeze your UI for a few seconds. (my project had ~20 gifs in it and the UI hanged for around 7 seconds when going back and forth through tabs)

I experience high CPU usage during animation.
