Add cron-daemon virtual package as an alternative dependency. This way pihole-meta by default still depends on cron, but allows installation of systemd-cron, which completely replaces cron daemon and package. With systemd-cron functionality of crontab files and /etc/cron.* directories works expected, as systemd-cron generates systemd timers from cron files.
