Add WebP image support

[jepsar]

Description

When you currently open a JPG image for example, it is shown in NetBeans. It would be great if you are able to view WebP images in NetBeans as well.

Use case/motivation

To check what an actual image looks like, it's faster when you are able to do so from NetBeans.

I guess we'd have to look at the option of plugins for ImageIO. The internal image viewer might also need adapting to support any ImageIO plugins available on the classpath.

Useful library for this and a few other image formats might be https://github.com/haraldk/TwelveMonkeys - BSD and pure Java solution.

To distribute maintenance overhead, a contribution in this area should also come with commitment to keep the libraries in sync and up to date. Updating library wrappers in netbeans is a bit more involved than bumping a maven dependency unfortunately.
