… when it never progresses past its DDoS protection page
Description
Fixes #1459
Fixes #1490
Sometimes (particularly with certain user-agents) Cloudflare will infinitely redirect you to another DDoS protection page; this can lead to infinite recursion. This change aborts after being forwarded 5 times.
Testing
Merge, set STORE=zotac, then "npm start run" until seeing "CLOUDFLARE RECURSION LIMIT REACHED, ABORTING"
New dependencies
None
