Be consistent on notation for packages

[athowes]

I see:

• {EpiNow2}
• {EpiNow2}
• EpiNow2

My preference is EpiNow2 (which is nowhere perhaps) but I don't mind as long as it's consistent here.

@zsusswein what is your preference?

[zsusswein]

• In markdown: {EpiNow2}
• In Roxygen docs: [{EpiNow2}][https://github.com/epiforecasts/EpiNow2]
  • Following: https://roxygen2.r-lib.org/articles/markdown.html#links

But if you're willing to put in the work to go through and standardize style everywhere, you can pick your preference because you're the one doing it!
