I would like to lay out my modules similarly to how I do it in Rust, such as below.

├── src
│    ├── main.nr
│    └─── foo
│         ├── mod.nr
│         └── bar.nr
└── Nargo.toml

This is not currently possible and I must do it this other way (which is also supported by rust)

├── src
│    └── main.nr
│    ├── foo.nr
│    └── foo
│         └── bar.nr
└── Nargo.toml

We should update how we look for modules in the file manager to support the first style of laying out imports as well. Note that we should error if I do the below.

├── src
│    ├── main.nr
│    ├── foo.nr
│    └─── foo
│          ├── mod.nr
│          └── bar.nr
└── Nargo.toml
