Faster inverse gamma and factorial for the WP 34S

If you combine the source code for the Digamma function with Dieter's Inverse Gamma function, the combined program is longer than Bit's original Inverse Gamma function (in RAM memory steps). It might be worth the extra memory space if it is significantly faster. But since it is not part of the standard flash library, it is not really fair to say it is a shorter program.
