inject require statements after require statements for the module we're autoloading plugins for

[kevinbarabash]

What this loader should actually be doing, is looking for files which load a particular module, e.g. "handlebars/runtime" and should insert the "plugin" modules afterwards, e.g.

const Handlebars = require("handlebars/runtime");
// other require statements

should be transformed to

const Handlebars = require("handlebars/runtime");
require("../path/to/handlebars-extras.js");
// other require statements
