Hyperlinks to files in `tree` mode

Discussed in #78

Let's say I have a code block like this:

```tree
(file.csv)[file.csv]
```

Would there be a way to attach a link to this file? The only way I can think about is with annotations via # (1)1. But inside there I would just write a message saying "LINK", which makes it quite repetitive if multiple files are present. Is there an easier way? Thanks!

Interesting idea, thanks for sharing 🙂

I suppose we could support the exec argument on tree blocks, in order to actually convert the contents from Markdown to HTML (as well as making a tree out of it).
