Moving from image::math::nq::NeuQuant to color_quant::NeuQuant

Hello there!

I have some old application in Rust which have this code:

let pal_q = image::math::nq::NeuQuant::new(1, PAL.len(), &PAL);
let mut ret = imageops::colorops::index_colors(&mut imgbuf, &pal_q);

image::math::nq::NeuQuant is deprecated, ok, using color_quant::NeuQuant and got error:

let pal_q = color_quant::NeuQuant::new(1, PAL.len(), &PAL);
let mut ret = imageops::colorops::index_colors(&mut imgbuf, &pal_q);

error[E0277]: the trait bound color_quant::NeuQuant: ColorMap is not satisfied

What happening?
