cvdl-ts: rendercv integration

[alpaylan]

We currently have a https://jsonresume.org integration that works pretty well. Users can import JsonResume documents, edit them on Tail, either render them using cvdl-ts or export back to jsonresume format.

I would like to have the same for https://github.com/sinaatalay/rendercv. @sinaatalay if you would be interested in a cooperation for that, I would love to talk for understanding what the best integration would be. Although there is significant overlap, I don't think the projects are necessarily in hard conflict of interest. As far as I understand, rendercv is much more opinionated in its design, whereas my future plans for Tail is to become a very general templating focused editor.

Hi! Tail seems like a lovely project! Unfortunately, I won't have time to work on RenderCV actively for a while. Also, I don't think we need to update some things on the RenderCV side to make it work, right? If you have any questions related to the schema, let me know.
