Animated WebP

Add support for loading and saving animated WebP files

Just ran across this issue too, only the first frame of the webp is rendered.

This would greatly increase performance on our site.

Out of curiosity, what is the complication with this? Is this just a matter of making sure webp are also converted using Wand? Or is Wand also not supporting animated webp as well? 🤔️

[kaedroho]

@hpoul there's no technical complication as far as I'm aware. Should be possible to do with Pillow using the append_images parameter on output: https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#saving-sequences

I would appreciate animated WebP files as well. Animated GIF support is not great, as ImageMagick needs a lot of cache resources even for smaller files, that we often cannot influence.
