docs: // GetCSV expects a data separator and one or n-parts of a URL to a resource which
  // can either be a local or a remote one.
  // The data separator can be a comma, semi-colon, pipe, etc, but only one character.
  // If you provide multiple parts for the URL they will be joined together to the final URL.
  // GetCSV returns nil or a slice slice to use in a short code.
