Set up a basic test and CI

I've added a CI definition which install gfortran on all windows, macOS and ubuntu. It's not running, see: https://github.com/USEPA/gflow1/actions/runs/10183578145

With this error:

prefix-dev/[email protected] and fortran-lang/setup-fortran@v1 are not allowed to be used in USEPA/gflow1. Actions in this workflow must be: within a repository that belongs to your Enterprise account, created by GitHub, or matching the following: cloud-gov/, docker/, r-lib/actions/, softprops/turnstyle@v1, zaproxy/, pypa/, uibcdf/[email protected], psf/black@stable, anchore/, release-drafter/, ruby/, aws-actions/, openjournals/openjournals-draft-action@master, gradle/gradle-build-action@, jamesives/github-pages-deploy-action@, azure/, aquasecurity/, dependabot/, SonarSource/, softprops/action-gh-release@, trufflesecurity/, rbhadti94/apache-jmeter-action@, trufflesecurity/trufflehog@, cypress-io/github-action@, peter-evans/create-or-update-comment@, peter-evans/slash-command-dispatch@, bahmutov/get-branch-name-by-pr@, bahmutov/npm-install@, release-drafter/release-drafter@v5, actions/, s4u/maven-settings-action@, gradle/actions/setu...

The problem here is that the USEPA Github organisation doesn't allow the setup-fortran action or the setup-pixi action.

To circumvent this temporarily, I've made a fork on my own namespace.
It's a bit slow to install gfortran on all operating systems (see fortran-lang/setup-fortran#98), but it's green!
See: https://github.com/Huite/gflow1/actions/runs/10183402742

It should be straightforward to get these actions allowed, they're not that obscure.

Trying closing and re-opening to see if that triggers the action
