FaIR rename; repo restructure; GWP tool
FAIR has been renamed FaIR: the acronym has changed to reduce confusion with an existing environmental policy decision model called FAIR.
Repository has been updated to include code coverage reports, pull request / issue templates, ReadTheDocs yaml and Makefile.
A Global Warming potential calculator has also been added.
No changes to science code from earlier in the 1.3 series.
