   * `:headers`             – When set to `true`, will take the first row of
       the csv and use it as header values.

      When set to anything but `false`, the resulting rows in the matrix will
      be maps instead of lists.

      length. Defaults to `false`.
  * `:unescape_formulas`   – When set to `true`, will remove formula escaping
