webp tools missing in image

[VasekPurchart]

Hello, stumbled upon this great project because I needed https://developers.google.com/speed/webp/docs/webpinfo .

I found it via https://command-not-found.com/webpinfo which I understand is a related project if Commando. And I think this issue lies probably more within that side of things, based on what I read in #3. But I have found no way to report it on that site.

Whichever of the WebP tools I try to install I get only a container with libwebp, but no actual runnable command (afaik), for example:

$ docker run --rm -it cmd.cat/webpinfo bash

If I install libwebp-tools i get all the relevant commands:

So as stated above, I think the installation instructions are incorrect, which then causes the image being built incorrectly. Hope my investigation will help :)
