[PRQ#67477] Deletion Request for cadence Rejected

Request #67477 has been Rejected by xyproto [1]: The project is archived at GitHub, but the package may still be useful, and a maintained fork may appear. If there is no maintained fork in 6-12 months, I agree that we should delete this package. [1] https://aur.archlinux.org/account/xyproto/
