`@fortawesome/fontawesome-pro` is a private npm module which requires login, making it difficult for anyone without npm access to start developing on compass. We barely use it, so it would be good going forward to remove it.
On first glance it might only be `compass-loading` which uses this package: https://github.com/mongodb-js/compass-loading/blob/master/package.json#L45
When removing it there also investigate to see if any other packages are using it and remove from there as well.
There's probably a free icon which we can use in place of the few pro ones we're using.
