Black is a rather heavy library to add as a mandatory dependency, and it's
not safe to assume it's always available everywhere (eg last I checked it's
not available through the Fedora repos).

I think leaving the conditional checks is needed, but its definitely it's
worth exploring if the dependencies can be added to the default windows
install...
