    build obs by running
        npm run build

    guid and uuid will be automatically generated and placed
    inside .env file which will then be read by the github workflow
    build script.

/*
    This script handles the following:
        - read package.json
        - create .env file
        - return uuid, guid, version

    can be called with the following external commands:
        - node obs.js                 returns version of obs
        - node obs.js generate        generates uuid / guid and shows all env vars in console
        - node obs.js uuid            returns obs uuid
        - node obs.js guid            returns obs guid
        - node obs.js versiom         returns version of obs

    can be called with the following obs commands:
        - npm run obs
        - npm run obs:generate
        - npm run env-obs
        - npm run env-uuid
        - npm run env-guid
        - npm run env-version
