Basic Node.js Support

[jamsinclair]

The library was intentionally built for the browser and web browsers.

Theoretically Node.js support should be possible, although I won't go out of my way to make this a core feature.

The main blockers I have found from experimentation:

• Imports need .js file extensions so they can be resolved by default node module system strategy
• Need to polyfill ImageData
• Need to manually read wasm binaries and compile to Wasm modules

I've fixed the import extensions and polyfilled ImageData in #40.

Users will still need to manually read and compile the Wasm modules themselves.
