feat: add kontent.ai CDN

[ref-thomasledoux1]

Added Kontent.ai CDN support.
Not sure how to run the tests locally, so couldn't verify this.

@ascorbic not sure if you get notified automatically, can't assign to you.

Hey. Is there a way of ensuring that the API uses a "cover" cover strategy when resizing? This isn't giving the expected aspect ratio: https://assets-us-01.kc-usercontent.com/b744f382-bfc7-434d-93e7-a65d51249bc7/cc0afdc7-23d7-4fde-be2c-f58ad54d2934/daylight.jpg?w=800&h=300

To run test tests locally you'll need the deno CLI installed, and then you can run deno test src

Hey @ascorbic I ran the tests locally now, should be passing now.
Also added a test for the "fit" behaviour.

Great! It looks like that one distorts the image, but fit=crop does the job: https://assets-us-01.kc-usercontent.com/b744f382-bfc7-434d-93e7-a65d51249bc7/cc0afdc7-23d7-4fde-be2c-f58ad54d2934/daylight.jpg?w=800&h=300&fit=crop

Ok, their docs weren’t really clear on this. Will adapt the logic.

[ascorbic]

Yeah. I ended up just randomly trying values!

Updated the code + tests

[ascorbic]

Great work! Thanks for this.
