docs: Creates a symmetry operation from a rotation matrix, translation
          vector and time reversal operator.
  
          Args:
              rotation_matrix (3x3 array): Rotation matrix.
              translation_vec (3x1 array): Translation vector.
              time_reversal (int): Time reversal operator, +1 or -1.
              tol (float): Tolerance to determine if rotation matrix is valid.
  
          Returns:
              MagSymmOp object
