Adding new R packages

This has been automated with the g6tr_package_setup() function. But please recheck all the points manually.

1. Create a new package inside the packages directory. Package folder should contain:

• R, tests, vignettes, data (optional), inst (optional), pkgdown folders
• DESCRIPTION, NEWS.md, .Rbuildignore files
• .Rprofile file. This should be the same as for all other packages.
• pkgdown/_pkgdown.yml file where functions and vignettes will be listed
• Nice to have: README.md and a HexSticker inside man/figures

2. Create an S3 folder for this package in docs.gradientmetrics.com

   • It needs to have at least register.html, signing.html and js/ files copied from another package
   • use _ instead of a . in the folder name

3. Adjust the main pkgdown.yaml to include the new package.

4. Extend GitHub Action builds executing R CMD CHECK for the new package

   • Copy Ubuntu workflow from the template workflow and put it to .github/workflows
   • Adjust names so that they reflect the new package (like g6tr.reports)
   • Adjust Linux dependency installation and R dependency installation steps in workflow with more specific instructions if needed; although sometimes the template code may be just enough
   • Extend main monorepo’s README.md with a new build checks/icons
