feat(core): export gosling svg logo

[sehilyi]

Can we include the SVG element of the Gosling logo image in the gosling.js library? This would make it easier for people to add a Gosling logo to their applications (e.g., "Powered by" labels). Helpful for some of our applications in the lab as well since we do not need to copy and paste the SVG code.

import react from 'React';
import * gosling from 'gosling.js';

return (
   ...
   {gosling.getGoslingLogoSVG(20, 20)}
)
