Migrate CI

[bmaupin]

The migration is already done, so it should just be a matter of updating README.md à la bmaupin/go-epub@8dc2323

Hmm, it seems Travis CI may no longer offer free builds for open-source projects: https://news.ycombinator.com/item?id=25338983

It might be better to migrate to GitHub Actions...

[bmaupin]

Try the starter template: https://github.com/actions/starter-workflows/blob/main/ci/node.js.yml

• Documentation: https://docs.github.com/en/actions/guides/building-and-testing-nodejs
• Examples
  • bmaupin/devops-cheatsheets@402e2c2
  • https://github.com/bmaupin/covid19-trends/blob/master/.github/workflows/build.yml

Then see if we can get coveralls working (see here for latest version: https://github.com/coverallsapp/github-action)

    - name: npm install, make test-coverage
      run: |
        npm install
        make test-coverage

    - name: Coveralls
      uses: coverallsapp/github-action@master
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }}
