-webp-loss command does not create webp image

If compression is impossible, a webp image is not created at all. I wish it could be controlled by flag. And pingo's lossless webp is fast, but the compression rate is lower than that of other tools..

the WebP lossless stuff in pingo is mostly very experimental — you could use cwebp
