setup-r

This action sets up an R environment for use in actions by:

• Downloading and caching a version of R by version and adding to PATH
• Registering problem matchers for error output
• Setting the following environment variables
  • NOT_CRAN=true
  • TZ=UTC
  • R_LIBS_USER=tempdir/Library
• Removing the -fopenmp flags from Makeconf on macOS, which are not supported with Apple's default Command Line Tools compilers.
