Use Pipenv instead of Pip + Virtualenv

[artis3n]

Versions locked by Pipfile.lock, simplifies the setup in the Wiki. Upgrade packages in future by running pipenv update. I don't have permission to update, but the Setup page of the wiki should now show:

setup infoz:

git clone https://github.com/carnal0wnage/weirdAAL.git
cd weirdAAL

pip3 install pipenv (if required)

pipenv install
pipenv shell

OSX Setup:

$ brew install python
$ pip3 install pipenv
$ pipenv install
$ pipenv shell

Then, all references to python3 can just be python as python 3 will be the only available interpreter inside the pipenv shell.

Hey @artis3n 👋 - I had not seen this PR until I got the notification about you closing it. Did you want to keep it closed or reopen?

Ah, no problem. Well, I'm conflicted. I think pipenv to automatically scope weirdaal's dependencies to a project-specific virtualenv would be beneficial, but people have issues with pipenv that are well summed up in: https://chriswarrick.com/blog/2018/07/17/pipenv-promises-a-lot-delivers-very-little/.

I feel that it's beneficial for weirdAAL's use case, but it's not so much a "definitely use this" as I originally thought when I opened the issue.

You may also want to lock the versions in the Pipfile, I've left them * (and rely on the Pipfile.lock to store the specific version needed).
