mhg_cython in python 3.9 and above about xlmhg

Thank you! I am incorporating xlmhglite into MEBOCOST updates to replace xlmhg. I will keep you posted if I met anything. Appreciate your help.

I'm working on patching this so mebocost can run -- looks like the pure python implementation is broken in Py3.8 as well, and you'll get the same error if you forcably use it, e.g. by adjusting the test runner at:

@zhengrongbin If you still require xlmhg, I have recently released a fork of this repository that supports Python>=3.8 and addresses some of the issues with the pure Python implementation of the algorithm.
