[feature request] support webp image format

[ustk]

If not too hard to implement, this would be nice to have, essentially when downloading an image from the server where every file is in this format already...

I'm in need of this as well.
Looks like there's a solution here:

Might give it a try this weekend.

@Christoph-Hart Any chance we can get this on your radar? Webp is the preferred image format for websites these days. It would be very helpful to be able to render them in HISE. I believe support was added in JUCE7?
