Surfacing option to save webp images in lossless mode.
Looking at libvips this param has been available for quite some time (7.38 I think) so didn't wrap it in a version conditional.
Just testing the water but if this looks ok I could have a go at surfacing some of the other webp options mentioned in #135 like
o.NearLossless
o.AlphaQuality
o.SmartSubsample
and potentially
o.WebpPreset
enumLet me know if that's ok, along with the naming, and I can give it a shot.
