Add build and publish workflow (#3)

This PR adds a workflow to build and publish the package. The package is published as a tgz file in build artifacts and releases.

Installation workflow from build artifact:
1. Download the build artifact, extract to see the .tgz file
2. `npm i -g <path_to_file.tgz>`
3. `watcloud-emails -h`

Installation workflow from releases:
1. Download the tgz file from a release
2. `npm i -g <path_to_file.tgz>`
3. `watcloud-emails -h`
