wip: move dashboard and cli into sub-crates

This change reduces the number of dependencies in the neptune-core crate.

The logical structure becomes:

neptune-core
├── Cargo.lock
├── Cargo.toml
├── cli
│   ├── Cargo.lock
│   ├── Cargo.toml
│   └── src
│       └── main.rs
├── dashboard
│   ├── Cargo.lock
│   ├── Cargo.toml
│   └── src
│       └── main.rs
└── src
    ├── lib.rs
    └── main.rs
