In this case Temme's method may fail as the incomplete gamma can't cope, but as the function changes over from 0 to 1 very rapidly, we can just use the saddle point as a reasonable starting location for iteration.
See https://github.com/scipy/scipy/issues/21725.
Use asymptotic expansion for very large a,b and add test cases.
Add some corrections to improve numeric stability.
Add better error handling of cases that explode so we get evaluation_error's.
* Update gamma.hpp
Missing name for Lanczos parameter in gamma_imp_final
* Update gamma.hpp
* Change location of void and annotate
