kayadata 0.4.3

This release is mostly a bug fix for changes in the way that the latest releases of ggplot2 and scales packages handle color names.

• Fix color in plot_kaya. Since scales v. 1.1.0, ggplot2 no longer recognizes "dark blue" as a color (now it must be "darkblue").
• Add visual regression tests for plotting functions (using vdiffr).
• Add optional arguments to plotting functions to override default colors.
• Add documentation site on GitHub Pages via pkgdown.
• Add code of conduct and guidelines for contributing.
