Overhauling and adding github actions - this PR instantiates gh actions with the CMD check and the next PR (Overhaul) will clean up the issues with the CMD check as they are now (some environment variables will need some changing I think)

Okay, with MacOS we can get through installing R 4.1.1, but now we're running into an issue here:

Run install.packages(c("remotes", "rcmdcheck"))
  install.packages(c("remotes", "rcmdcheck"))
  remotes::install_deps(dependencies = TRUE)
  shell: /usr/local/bin/Rscript {0}
  env:
    R_LIBS_USER: /Users/runner/work/_temp/Library
    TZ: UTC
    _R_CHECK_SYSTEM_CLOCK_: FALSE
    NOT_CRAN: true
Error: An error occurred trying to start process '/usr/local/bin/Rscript' with working directory '/Users/runner/work/Syndemics/Syndemics/Syndemics'. No such file or directory

I'm not familiar with how environment works on MacOS, but it appears that Rscript isn't in the runner's $PATH, so the command can't be found after R is installed. I presume once that gets resolved the check will pass.

Requesting changes to the workflow to ideally get the check to pass.
