  Oblate spheroidal radial function obl_rad1 for precomputed characteristic value

  Computes the oblate spheroidal radial 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`. Requires pre-computed characteristic value.

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