Changing the default image sizes that are generated <g-image> component

[t9luke]

Summary

The default image sizes can be changed by editing this line of code let imageWidths = options.imageWidths || [480, 1024, 1920, 2560] (line 97) in the file node_modules\gridsome\lib\app\queue\ImageProcessQueue.js

It would be useful if they could be modified inside gridsome.config.js

Basic example

module.exports = {
  images: {
    imageWidths: [992, 1600, 1920, 2560, 3840]
  }
}
