Add pie chart nodes

[eturkes]

Thank you for your work on visNetwork, it is an immensely useful package. However, one useful feature missing that I like to use in igraph is the ability to use pie charts as nodes, as seen in the attached image. It would be awesome if this were implemented and others have expressed interest as well (https://stackoverflow.com/questions/48204432/visnetwork-pie-chart-nodes).

I would like to have this added as well.

Something like pie charts as node would be also useful to me, but maybe using ggplot2 or grob objects as nodes would provide more possibilities.

This would also be super helpful for me too.
