that has the handle `foo@bar.com` but whose profile is at the URL
`https://mastodon-bar.com/users/foo`, would be purged by either
`tootctl domains purge bar.com` or `tootctl domains purge --by-uri mastodon-bar.com`.
When the --include-subdomains option is given, not only DOMAIN is deleted, but all
subdomains as well. Note that this may be considerably slower.
When the --purge-domain-blocks option is given, also purge matching domain blocks.
