Hello, I want to ask if the charmbracelet community would be interested in accepting a PR for adding a tree model to the project.

A while ago I needed one for a project of mine and at the time there was none available, so I created one.

Currently I think it reached a level of maturity that other people might be interested in using it.

If anyone can have a look at the code, and the example, let me know if it would be accepted as a PR.
