  Prolate spheroidal angular function of the first kind and its derivative

  Computes the prolate spheroidal angular function of the first kind and its derivative (with respect to x) for mode parameters m>=0 and n>=m, spheroidal parameter c and `|x| < 1.0`.

  Returns: | s Value of the function sp Value of the derivative vs x
