 Provide custom search commands to update [malware-filter](https://gitlab.com/malware-filter) lookups. Each command downloads from a source CSV and emit rows as events which can then be piped to a lookup file or used as a subsearch. Each command is exported globally and can be used in any app. This add-on currently does not have any UI.
