Custom publicPath option

[kenrick95]

As I understand, this plugin right now only reads from webpack output publicPath.

One use case for this is that site assets are served at CDN but would like to serve manifest.json under own site (i.e. non-CDN). At current configuration, where manifest.json is served at CDN (which has different origin from own site's origin), Chrome will throw this warning: Manifest: property 'start_url' ignored, should be same origin as document. at console.

I realized that there is no way to specify custom publicPath yet for this plugin and would like to have that option.

Thanks
