[Feature request] Option to download list of intersecting elements

[adomingues]

Hi @asntech,

I am big fan of this tool -thank you!

Recently I started missing a feature which is very important for my colleagues: the ability to download the overlapping (and exclusive) list of genes. Say in a two away venn / upset download the genes which are common to A and B, but also the ones which found only in one or the other.

Something along these lines:

• upset https://stackoverflow.com/questions/65027133/extract-intersection-list-from-upset-object
• venn https://stackoverflow.com/questions/23559371/get-the-list-of-items-in-venn-diagram
