automating the install of pulsar-client and pulsar-client-dev

Another package I use (node-sass) downloads and builds its native dependencies automatically.
It does this by using npm's install and post install hooks: https://github.com/sass/node-sass/blob/887199a28fbed12f18dfecbfa5495aa5d48b2d4e/package.json#L31
their install script: https://github.com/sass/node-sass/blob/master/scripts/install.js
their postinstall script: https://github.com/sass/node-sass/blob/master/scripts/build.js

automating the install of pulsar-client and pulsar-client-dev would make it much easier to use this library.

Start by inspecting this repository's package.json and its current native dependency installation path, then compare them with the node-sass install.js and build.js examples linked in the issue. The work is done when installing the Node package automatically installs or builds pulsar-client and pulsar-client-dev without the manual steps the issue describes.
