Add helper fn to return hashmap w/ react lifecycle methods to specify WebGL canvas components (but without requiring additional deps)

Thanks for making this library! I'm looking forward to playing with it :)

One thing at a glance - I downloaded some basic sphere model from turbosquid and it comes with some material. When I load it via webl-obj-loader and console.log the mesh returned from downloadMeshes I see there's some materials.

Looking the [source of material.js](https://github.com/frenchtoast747/webgl-obj-loade

New features and suggestions

This may be a little out of scope for the project, but I'd love to hear your take. For my specific needs, users will upload .obj file to a server, and then a web player build will pick it up and use your library to load it into the scene asynchronously. Easy peasy.

Trouble is, that files are big. They are representations of BIM models, where the .obj is easily

I currently suspect that not all bytes are properly exported:
I could not find sprites or textures for the fonts. I still suspect them in this file somewhere
Even if they can not be found here, this is still a useful feature to have for debugging.
