feature request: support venn diagrams

[derekperkins]

It would be awesome to have native visx support for Venn Diagrams. Most of the heavy lifting on the math side has already been implemented in conjunction with d3 (see references).

Interesting! Haven't seen these done in d3 before, thanks for the examples / prior work links.

Definitely happy to help review PRs if someone is interested in adding a @visx/venn or @visx/venn-diagram package 🎉
