Parallelize ignores `force` flag in options for publisher

when I do this: 
```
.pipe( parallelize( publisher.publish({
          "Cache-Control": ( process.env.FLO_ENV === "prod" ? "max-age=3600, no-transform, public" : "max-age=120, no-transform, public" )
        }, { force: true } ), 10 ) )
```
it does NOT force them to be created.
