Add Github Actions to publish to Cocoapods and npm (#169)

Fixes #166.

This is preparatory work to publish to the averred package managers.

Still to happen for first release:

- Add an `NPM_TOKEN` to npm.
- Tag the release as `0.28.3-0`
- Perform the release.

After the first release, we still need to:

- verify releases happen
- update the podspec template 
- update the documentation about pre-releases.

Subsequent releases, we should think about automating:

- update the `package.json` and ``Cargo.toml` version numbers.
- rotate the `CHANGELOG.md` (currently we don't have a change log).
- tag the release
- do the release
