feat(gatsby-plugin-utils): enable tracedsvg

[wardpeet]

Description

Enable traced SVG for image cdn and convert all implementations to our own @gatsbyjs/potrace with GNU 3 License to be compatible with MIT.

I've updated all potrace usage

Very nice! :) What benefit does @gatsby/potrace give us over the original package?

Just pitching here in support of this, our team is blocked heavily since the original package has the viral GPL license. Our clients can't move forward without assurance that all code we use is compliant with their particular license agreements

I upgraded the license to GPL v3 (which is allowed by their License) and GPL v3 is compatible with MIT

[TylerBarnes]

Amazing, I was wondering how that would work 👍

in Readme there is still noted v2:

The GNU General Public License version 2 (GPLv2).

GPL v3 is compatible with MIT

(I assume this means LGPLv3, per this thread and https://github.com/gatsbyjs/node-potrace/blob/f182e9e/LICENSE)

Lesser GPL isn't interoperable as it looks. The wording can be muddy as it wasn't written with scripting languages and package systems in mind.
