It fails when used as `cargo osha`

I expect it to scan the whole crate/project, but instead it tries to open a non-existing file osha:

$ RUST_BACKTRACE=1 cargo osha

As it says in the readme, Not actually a cargo plugin yet. :disappointed:

[dtolnay]

Workaround: rustup run nightly cargo-osha.

@dtolnay , Or just use cargo-geiger, which is based/inspired by this project.
