Add support for Authorizations resource

[trevornelson]

Adds support for Authorizations resource from the Unit API. For now, we're only concerned with the list endpoint, and just pulling in the bare minimum fields for now to fix an issue where the dashboard doesn't show recent transactions. We can circle back later if we want to start pulling in rich merchant data or any other fields on the authorization resource.

@trevornelson I think you need to bump the version in lib/unit-ruby/version.rb but tbh I don't think I've ever made a change to this gem myself. @ianyamey can you confirm?

Yes, you’re right! We’ve been following semver so this should probably be a bump of the minor version

@Eitansbd @ianyamey Yep! The readme made it seem like the convention was to get it reviewed first and then bump the version. I can update the readme to just have it all in one PR review though- I think that's a bit less hassle anyway.
