Tool for quantizing PNG images in RGBA format

Pngnq is a tool for quantizing PNG images in RGBA format. Pngnq is an adaptation by Stuart Coyle of Greg Roelf's pnqquant using Anthony Dekker's neuquant algorithm. The neuquant algorithm uses a neural network to optimise the color map selection. This is fast and quite accurate, giving good results on many types of images.
