Add OSC 8 hyperlinks

[NDagestad]

In something like tree where sometimes the list can be very long and getting the path of a file out of the tree output is not necessarily trivial, having terminal hyperlink is really nice !

I have used a variation of this PR for a few month now without any issues (but I reworked it a bit before making the PR so a bug could have sneaked in there).

Hi @NDagestad, this is great; I came to the repo precisely in order to look to see whether anyone had started work on this feature.

Currently, your PR only supports file:// links. I'd like to suggest following e.g. ripgrep and delta by making the hyperlink format configurable, perhaps by adding an option --hyperlink-format as ripgrep does.

This will allow tree to create links that open in a specific editor/IDE with whatever behavior is desirable for that editor/IDE (e.g., opening the file in the correct project workspace). It also allows users to register custom URL protocols with their OS to implement arbitrary on-click behavior and/or to route the click to an arbitrary HTTP service (personal project e.g.), etc.

I am not quite sure how I feel about changing the scheme like that, I'll play a bit around with it this weekend to make up my mind about it. 🤔 And also maybe email the author, because I am not sure if contributing to the github is the proper way to contribute to tree.
