Removes locally thumbnails for previews.
The --days option specifies how old preview cards have to be before
they are removed. It defaults to 180 days.
With the --background option, instead of deleting the files sequentially,
they will be queued into Sidekiq and the command will exit as soon as
possible. In Sidekiq they will be processed with higher concurrency, but
it may impact other operations of the Mastodon server, and it may overload
the underlying file storage.
With the --dry-run option, no work will be done.
With the --verbose option, when preview cards are processed sequentially in the
foreground, the IDs of the preview cards will be printed.
With the --link option, delete only link-type preview cards.
