Feature Request: WebP support in Statiq.Images

[shmatt]

Lighthouse reports (available in Chromium Devtools) is used to anaylise optimisation of a web page.

A common suggestion it makes is to use modern image formats, including WebP. ImageSharp now supports WebP, making it trivial to add to Statiq.Images

   /// <summary>
    /// Outputs the image as WebP. This will override the default
    /// behavior of outputting the image as the same format.
    /// </summary>
    /// <returns>The current module instance.</returns>
    public MutateImage OutputAsWebp()
    {
        _operations.Peek().OutputActions.Add(
            new OutputAction((i, s) => i.SaveAsWebp(s), x => x.ChangeExtension(".webp")));
        return this;
    }
