refactor: Add new PlPath that abstracts over URI and PathBuf

No description provided.

I am not sure about calling it Address, this to me gives the feeling of referring to a network server rather than the location of a file / folder. Could we maybe call it enum PlPath / struct PlCloudPath instead?

nit: maybe call it strip_scheme()?

Could we directly use &PlPath / &PlCloudPath instead of a separate Ref type?

This would mean you require cloning str into Box<str> always. But might not be that much of a problem, honestly.
