Go+Wasm image dithering tool

Load an image, click Go and wait (potentially for a while) for the image to be dithered using the Nord color palette and the Floyd-Steinberg algorithm.

Performance isn't great, as Go+Wasm only runs on a single thread. The Wasm call also blocks the rendering (that would be fixable, though).

If you're into that sort of thing, source code is available on GitHub.
