      Parses window and nperseg arguments for spectrogram and _spectral_helper.
      This is a helper function, not meant to be called externally.
  
      Args:
        window : string, tuple, or ndarray
          If window is specified by a string or tuple and nperseg is not
          specified, nperseg is set to the default of 256 and returns a window of
          that length.
          If instead the window is array_like and nperseg is not specified, then
          nperseg is set to the length of the window. A ValueError is raised if
          the user supplies both an array_like window and a value for nperseg but
          nperseg does not equal the length of the window.
        nperseg : int
          Length of each segment
        input_length: int
          Length of input signal, i.e. x.shape[-1]. Used to test for errors.
        dtype: dtype for window if specified as a string or tuple. Not referenced
          if window is an array.
  
      Returns:
        win : ndarray
          window. If function was called with string or tuple than this will hold
          the actual array used as a window.
        nperseg : int
          Length of each segment. If window is str or tuple, nperseg is set to
          256. If window is array_like, nperseg is set to the length of the window.
