Locking down packages manually until pipenv matures enough

Sadly due to several issues with Pipfile.lock, it seems to either hang or take forever as seen here pypa/pipenv#2284 here pypa/pipenv#1816 and here pypa/pipenv#356 making it extremely unusuable
For that reason instead of switching to an alternative solution, I have decided to pin all the dependencies so that this project doesn't start failing with breaking changes in the future
I will probably come back here and generate lock and use semver minors/patches only once pipenv have matured enough, good luck to its developers!
