Is your feature request related to a problem? Please describe.
No, simply want to support a more modular approach to initializing this package to prevent having to pollute the window with hljs.

Describe the solution you'd like
To be able to pass hljs as a variable in an initializer function/factory/etc. for highlightjs-line-numbers.js to prevent having to bind hljs to the window first.

Describe alternatives you've considered
