Change 'master' to 'main' in place from local Github clone

The scenario:

You have a local clone of a Github-hosted repo with master as the default branch
Optionally, you have the hub command-line tool installed
- https://github.com/github/hub
Optionally, you have a Github Personal Access Token that can write to the relevant repos
- https://github.com/settings/tokens
- Only needed if you want to change the default branch from the CLI versus the Github UI

	#!/usr/bin/env bash

	# Get ahead-behind status for current branch against _all_ remotes
	# To use, put this executable script anywhere on your PATH

	# TODO make git alias instead of a PATH git-<command> executable

	BRANCH=$(git branch --show-current)
	# Could override branch with argument but let's keep it simple
	# BRANCH=${1-${BRANCH}}

	#!/usr/bin/env python3
	"""Endless March"""

	from datetime import datetime
	import subprocess

	actual_date = subprocess.run("date",capture_output=True, text=True)
	actual_date_parts = actual_date.stdout.split()

	today = datetime.now()
