Get regional Carbon Intensity data ( https://www.carbonintensity.org.uk/ ) and display it on Inky Frame

	"""
	This example connects to the Carbon Intensity API to give you a regional forecast of how
	your (UK) electricity is being generated and its carbon impact.

	Carbon Intensity API only reports data from the UK National Grid.

	Find out more about what the numbers mean at:
	https://carbonintensity.org.uk/

	Make sure to uncomment the correct size for your display!
