docs: Construct an empty byte-aligned array for efficient use by :mod:`pyfftw`.
      This function is a wrapper for :func:`pyfftw.empty_aligned`
  
      Parameters
      ----------
      shape : sequence of ints
        Output array shape
      dtype : dtype
        Output array dtype
      order : {'C', 'F'}, optional (default 'C')
        Specify whether arrays should be stored in row-major (C-style) or
        column-major (Fortran-style) order
      n : int, optional (default None)
        Output array should be aligned to n-byte boundary
  
      Returns
      -------
      a :  ndarray
        Empty array with required byte-alignment
