Label internal nodes

[stephenshank]

Add option to display internal node labels.

This could be implemented by providing a custom node styler. I think you could modify the following line to check the setting and to apply this internal node styler before applying the custom node styler: https://github.com/veg/phylotree.js/blob/bfb49ba111c4124b4aa637b5a9f495d07b05cf2e/phylotree.js#L2337-L2341

If you'd like me to try to write that into a pull request, let me know!
