Error: image.max is not a function

[retan]

Usage of max configuration option causes an error image.max is not a function.
From what I can tell the error comes from sharp, and occurs because the max function was deprecated - see: https://sharp.pixelplumbing.com/changelog#v0210---4supthsup-october-2018

Since this project seems to be inactive, even just for the moment (#111), I've gone ahead and created a completely new plugin for this purpose on my own: https://github.com/robinloeffel/gulp-rezzy. It uses sharp under the hood, as well.

Sharp max function is deprecated. Instead we need to use the Sharp fit param.
I made a pull request that add the fit param to gulp-responsive config : #146
