Inkscape is an open source project with a built in image trace tool. The code could be repurposed for this application. It's licensed under the GPL v.2 https://gitlab.com/inkscape/inkscape I'm sure someone else might have suggested this, but I hope my post helps to vote for this feature to move from the backlog and into development. It's surprising to find this post has been here for over 6 years.
