NativeScript randombytes shim

The randombytes package doesn't work in the {N} runtime, so replace it by this package if you need to.

Installation

``sh
tns plugin add nativescript-randombytes
`

Usage

`js
var randomBytes = require('nativescript-randombytes');

// sync usage
console.log("randomBytes: " + randomBytes(16));

// async usage
randomBytes(16, function (ignore, result) {
console.log("randomBytes async: " + result);
})
``
