Add special handling of iCloud Private Relay domains
Implement special handling of Apple iCloud Private Relay domains to prevent Apple devices from bypassing Pi-hole. The default setting is to enable this feature, hence Private Relay (...) will be disabled. You can turn it off by setting BLOCK_ICLOUD_PR=false in /etc/pihole/pihole-FTL.conf followed by a pihole restartdns
