Enable black for Python 3.7 once fixed
Thanks for logging an issue with `ptr`. Here are some questions to help try 
and pull out as much information possible to help us help you!

## How is `ptr` not doing what you expect?
Today, we don't run black with Python 3.7 on Windows

## What is your suggestion to make this better?
Once black works - enable it and remove hacks

## How can a developer reproduce this?
Run `black.exe` with Python 3.7 on Windows

- We could potentially also add a allowed to fail run on Azure if available ...
