§Color quantization library
This library provides a color quantizer based on the NEUQUANT
Original literature: Dekker, A. H. (1994). Kohonen neural networks for optimal colour quantization. Network: Computation in Neural Systems, 5(3), 351-367. doi: 10.1088/0954-898X_5_3_003

§Usage
let data = vec![[0; 4]; 10];
let nq = qwant::NeuQuant::new(10, 256, &data);
let indixes: Vec<u8> = data.iter().map(|&pix| nq.index_of(pix) as u8).collect();
let color_map: Vec<[u8; 4]> = nq.take_color_map();
