Packaging in CI (#59)

* CI: added packaging recipe

* Simplification

* Same workflow

* Using artifacts

* Prefixing tests with 'command' for GH workflow

* Bumped 'actions/checkout' to v4 to silence Node.js deprecation warning

* Ensuring tests are executable

* Chmod'ing before running test

* Compress/uncompress artifacts to preserve files permission

* Dropped chmod

* Dropped extra path

* Updated path

* Only build package on new tag
