Fix vectorize node to return SVG data compatible with SaveSVGNode

- Change RETURN_TYPES from (IMAGE, SVG) to (SVG,) - only return SVG
- Add SVGData wrapper class to match RecraftIO.SVG format for SaveSVGNode
- Remove unnecessary image conversion logic (no more cairosvg dependency)
- Simplify to only handle imageBase64Data response from API
- Return SVG content wrapped in SVGData compatible with SaveSVGNode
