From 908cc6f8d300394bd8e777846ace6181393ad18e Mon Sep 17 00:00:00 2001

Subject: [PATCH] Move __version__ into __init__.py

A little bit of clean parsing code in setup.py and the enforcement
from `black`, and it becomes possible to ditch a file which only held
a single value. Similarly update the version parsing in the makefile.
