Adds support for encoding WebP images using libwebp to ImageSharp.
When ImageSharp 2.x encodes transparent images with compression, the file size is larger then even doing lossless webp encoding. This was fixed in ImageSharp 3.x, but with the new license this isn't feasible to all projects. So this makes it possible to encode transparent WebP images properly on ImageSharp 2.0.

If running or deploying on Linux you need to install libwebp-dev.
