Include Cache-Control Headers

[kespinola]

Background

When the service being proxied by cloudflare sets Cache-Control header cloudflare will forward the header along to the browser which triggers it to lookup the context from its local cache instead of requesting from cloudflare.

Goal

Users that have viewed an image before from their browser serve images from local cache instead of requesting again from cloudflare.

Requirements

When image successfully resized set Cache-Control header max-age to trigger local cache lookups from a browser.

[mpwsh]

Added Cache Control headers to each response after image has been download/resized.

See PR #2

I can see images being cached by the browser.
