Common design/template for package landing pages

[sgibb]

It would be great to have a common (corporate) design for all of our package landing packages/pkgdown sites, e.g. https://rformassspectrometry.github.io/MsCoreUtils/

Something similar to https://github.com/tidyverse/tidytemplate (see e.g. https://dplyr.tidyverse.org/).
Maybe an own color scheme (based on the one used in the stickers) would be a good start.

That would be really cool - I haven't had time to get into this.

It would also be nice to have custom URLs: MsCoreUtils.RforMassSpectrometry.org, Spectra.RforMassSpectrometry.org, ... I tried by haven't managed to set up the domain properly so far.
