Title: Explicitly require barcode type (barby no longer does this by default)

Barby no longer requires the various symbology types by default, meaning that we need to explicitly require the `type` as part of the configuration. Following your lead, I've required the `type` in the same fashion that you've required the `outputter`. Pretty straight forward.

Also, I updated the read me to explain why this is a good gem to use with heroku. I actually tried a few options before arriving at `has_barcode`. I think this little addition would be helpful.

Thanks for building this!
