Add sunbustR functionality?

[nklepeis]

Hi, Fantastic visualization tool! I am pursuing the development of sunburst-type visualization that combines the coffee-wheel interactivity with areas mapped to node values (e.g., counts, time spent) as sunurstR and others do. This way the tool can be used to explore conditional probabilities.

Thanks, @nklepeis! This package, unfortunately, is pretty outdated and I won't be able to update it to include this type of a functionality any time soon. I will keep this issue open for the records but apologies if this won't get done.
