Promotional component for various purchase call to actions.
Promo molecule has two possible layouts (based on current designs). In its default form, it forms a single column, with a media element, text content and a call-to-action.
There are a few different types of element that can go in the media container of this component, including Avatar, StandardOrgLogo and IconInCircle.
The `isWide` variant moves the image to the left of the text content.
The `isUnlimited` prop adds the unlimited 'triangle' branding elements to the background of Promo.
