label clades

[tzaquin]

Hi there,

First I'd like to say that I really love your work. It has been extremely useful lately.

I would like to ask, I've been trying to label my species tree clades with images or custom emojis. I could not find a way to actually load them using the geom_cladelabel.

On the parent node, I do manage to add an image and phylopic but it would be nice adding it as a cladelabel.

Thank you,

Tal
