panic with add with overflow when converting with vtracer #11

Hey!
I've found an issue, that I can reproduce both in the CLI, and on the website: https://www.visioncortex.org/vtracer.

When I upload the image attached from https://unsplash.com/photos/medium-short-coated-white-dog-lying-on-green-grass-field-LATYeZyw88c it crashes due to attempt to add with overflow.

Full logs:
