returns a pair of acceptance functions, first the unnormalised one for
fitting, then the normalised one for generation
The minimum and maximum of the range of the time variable implicitly
defines the position of the first and last knot. The other knot positions
are passed in knots. Conversely, the coeffs parameter records the height
of the sline at all but the last two knot positions. The next to last knot
coefficient is fixed to 1.0, thus fixing the overall scale of the
acceptance function. The spline coefficient for the last knot is fixed by
extrapolating linearly from the two knots before; this prevents
statistical fluctuations at the low stats high lifetime end of the
spectrum to curve the spline.
