docs: Converts the given `plunge` and `bearing` in degrees to a strike and dip
      of the plane whose pole would be parallel to the line specified. (i.e. The
      pole to the plane returned would plot at the same point as the specified
      plunge and bearing.)
  
      Parameters
      ----------
      plunge : number or sequence of numbers
          The plunge of the line(s) in degrees. The plunge is measured in degrees
          downward from the end of the feature specified by the bearing.
      bearing : number or sequence of numbers
          The bearing (azimuth) of the line(s) in degrees.
  
      Returns
      -------
      strike, dip : arrays
          Arrays of strikes and dips in degrees following the right-hand-rule.
