Color quantization library

This library provides a color quantizer based on the NEUQUANT quantization algorithm by Anthony Dekker.

Usage

let data = vec![0; 40];
let nq = color_quant::NeuQuant::new(10, 256, &data);
let indixes: Vec<u8> = data.chunks(4).map(|pix| nq.index_of(pix) as u8).collect();
let color_map = nq.color_map_rgba();
