Allow for installing via npm

[massi-ang]

In order to simplify development and inclusion of this package in own logic, could you please make the package installable via NPM, by either publishing to npomjs.com or adding a package.json file at the root of the Github repo.

This would be appreciated

You can install the full Greengrass SDK from npm by doing npm i aws-greengrass-core-sdk. Then you can use stream manager by importing const sm = require("aws-greengrass-core-sdk/stream-manager")

Keeping this issue open as we should publish this to npm standalong, but you do have a simple option to use the full SDK which includes stream manager.
