Add breadcrumbs functionality

[jtmkrueger]

It'd be cool if the extension showed the current directory you were in at the top of the tree using the vscode breadcrumbs. It could be tied to the breadcrumbs setting in vscode so people that don't have breadcrumbs on wouldn't have to see it.

I can try and do a PR for this, just don't want to take the time if it's not something you'd be interested in merging

@jtmkrueger I'm not against this feature (although I don't personally use breadcrumbs, so it's not a high priority) but I would actually be surprised if vscode gives you an extension API for controlling this bit of UI.

If the code required for setting them is minimal, then I'd happily merge the PR, but before you set off implementing can you send the links to the docs for the API for interacting with the breadcrumbs from an extension codebase?

[jtmkrueger]

I was going to research how the vscode module's breadcrumbs api works. You're probably right, but I didn't wanna dig in on anything if it wasn't something you'd accept PR's for.
(Really digging the extension thanks for making it! I use it with the VSCode Neovim extension and it was super easy to set up.)

I actually don't use breadcrumbs in my editor tabs either but I think it might be helpful here (perhaps as an opt-in feature).
