Should we add a pkgdown web site?

Should we add a pkgdown web site? It might be a better linkable resource for describing the project. I think the effort required is low. The basic procedure is at https://pkgdown.r-lib.org/

We would need to do these things:

• Add .github/workflows/pkgdown.yaml by stealing pkgdown.yaml
• Add _pkgdown.yml
• Make a NEWS.md formatted like NEWS.md, while stealing and summarizing CHANGELOG content from psofa and nSOFA_calculation
• Maybe add this to .RBuildignore

^_pkgdown\.yml$
^docs$
^pkgdown$

• Maybe add this to .gitignore

I did the NEWS.md work as of release 0.2.0
