docs: r"""Import time-stamp events from an annotation file.  The file should
      consist of a single column of numeric values corresponding to the event
      times. This is primarily useful for processing events which lack duration,
      such as beats or onsets.
  
      Parameters
      ----------
      filename : str
          Path to the annotation file
      delimiter : str
          Separator regular expression.
          By default, lines will be split by any amount of whitespace.
  
      Returns
      -------
      event_times : np.ndarray
          array of event times (float)
