Don't let setup.py import __init__.py

[proItheus]

Currently, pip install git+https://github.com/MXWXZ/sjtu-automata will throw error like this

error: subprocess-exited-with-error

Try manually install the requests library?

For me personally, this piece of code looks quite "suspicious" (evil eval). Probably moving helper functions in __init__.py to an independent file is a better choice?
Anyway, thanks for your help. I may take a look this weekend and you are free to refactor this!
// Refactor the code to rust/golang could be even better (especially for windows users) :P.
