DVC badge

thought it would be great to have a DVC badge - mainly for devs to note we're using it

[Casyfill]

theoretically it might be even better if it show current version/tag for data

Great idea! We will definitely create our own one later and will host it ourselves, since badges on shields.io tend to not load pretty frequently. We actually were using shields.io for our current badges, but switched back to default ones exactly for that reason.

Thanks,
