Possibility of having set legends

This is more a suggestion rather than an issue. Sometimes it is very useful to have color legend in addition to the counts legend. This can be turned off/on by user if the parameter 'show.legend' can be set in the call.

sorry to delay response.

In default, we used different colors of set edges to separate different sets. So we hide the legend to simplify the graph.

If you want to show the legend of set, just refer to the document vignette at: https://gaospecial.github.io/ggVennDiagram/articles/fully-customed.html.
