Creating rust dependencies tree explorer

Hello!

I tried to implement a tree view that shows the dependencies of a project.

It allows to see all dependencies to the project and it uses `cargo tree` for it. Also it allows to click and open the files, the viewtree tries its best to follow the openned file in the editor.

Here is an example:

Any feedback is welcome since i have basically no professional experience with TS.
