docstr: ivy.Container instance method variant of ivy.hann_window. This
  method simply wraps the function, and so the docstring for
  ivy.hann_window also applies to this method with minimal changes.
  
  Parameters
  ----------
  self
      input container with window sizes.
  periodic
      If True, returns a window to be used as periodic function.
      If False, return a symmetric window.
  dtype
      The data type to produce. Must be a floating point type.
  out
      optional output container, for writing the result to.
  
  Returns
  -------
  ret
      The container containing the Hann windows.
  
  Examples
  --------
  With one :class:`ivy.Container` input:
  
  >>> x = ivy.Container(a=3, b=5)
  >>> ivy.hann_window(x)
  {
      a: ivy.array([0.0000, 0.7500, 0.7500])
      b: ivy.array([0.0000, 0.3455, 0.9045, 0.9045, 0.3455])
  }
