Research direction

Start by reviewing the existing C++ addon examples and the Node.js N-API ArrayBuffer documentation. Determine how an ArrayBuffer created in JavaScript can be passed to a N-API function and how decoded image memory should be copied into it. Done means a clear working example covering this image-buffer workflow.
