v1.1.0

Minor improvements

• The Comparing Groups R Markdown template now starts with a Background section
  which has a sub-section called "Original Data", under which is a link to
  download the original data file, which is embedded using xfun::embed_file().
• The print_results() function now has a sig_color argument, which specifies
  what color to print results when they are significant. This is implemented
  using a Pandoc Lua filter, which is automatically copied to the working
  directory when rendering the Comparing Groups R Markdown template.
