A module to generate performant HTML image markup for images hosted on assets.ubuntu.com. The markup will:
Use data-src attributes for lazysizes
Use predefined srcset break points
Resize the image with ?w=XX&h=XX query parameters
Prefix all image URLs with cloudinary proxy URLs, for CDN and image transformations
Parameters

alt (mandatory string): Alt text to describe the image
width (mandatory integer): The number of pixels wide the image should be
height (mandatory integer): The number of pixels high the image should be
