Feature Request

As with the subdirectory option on git dependencies, it would be nice to be able to install from urls pointing to archive files where the target project is not at the root level. This is convenient for example when installing from the archives GitHub automatically creates for tags, like https://github.com/{owner}/{repo}/archive/refs/tags/{tag}.tar.gz.

It's worth noting that pip does support it, e.g.:

myproject @ https://github.com/{owner}/{repo}/archive/refs/tags/{tag}.tar.gz#subdirectory={myproject_dir}

Although it doesn't seem to be explicitly documented.

As a side note, I guess that support for the subdirectory option could be added for local archive files too, that is when providing a path dependency. But that implies also supporting it when the path is just a directory, which seems quite pointless.
