Add WebP module ~1.0 and enable by default

Problem/Motivation

WebP
https://www.drupal.org/project/webp

WebP is an image format introduced by Google with the aim of improving the size and performance of images on the web.

In Google's own words :

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

The promise is to save around 20 to 30 percent of space on images using WebP and, as you'll see in this article, this claim is consistent with the results I've found myself using WebP in Drupal.

I won't go into more details about WebP, but if you are interested in more information about the subject please visit this link: https://developers.google.com/speed/webp/.

There is also a comparative study between jpeg and WebP, and the advantages of using WebP. You can read it here: https://developers.google.com/speed/webp/docs/webp_study
