/**
* Inspired by https://github.com/IronCoreLabs/recrypt-node-binding
* ==================================
*
* This script is responsible for compiling and building the NPM release bundle for this repo. The following steps are taken:
*
* + Clean up any existing Rust builds by running `cargo clean`.
* + Run `cargo update` to make sure all dependencies are available.
* + Compile rust code into index.node file.
* + Run unit tests to ensure the library is in good shape for publishing.
* + Move all expected content into a `dist` directory.
* + Generate a binary distribution in `bin-package`.
* + Do a dry run of npm publishing via irish-pub or perform an actual publish step if `--publish` option is provided.
