Enhancement: Global CLI

[JacobCoffee]

Create a global CLI to run any given years code, where the code is in any given language, and we can run any day and its parts individually.

The structure will probably maintain this format:

$year/$language/$day.$langext

Currently this is like:

├─ 2023
│  ├─ Data
│  ├─ Rust
│  │  ├─ src
│  │  │  ├─ days
│  │  │  │  ├─ dayX.rs
│  │  │  │  ├─ dayY.rs
│  ├─ Python
│  │  ├─ Day_X
│  │  ├─ Day_Y
│  ├─ OCaml
─ 2022
│  ├─ Data
│  ├─ Python
│  │  ├─ Day_X
│  │  ├─ Day_Y
│  ├─ Rust
│  │  ├─ src
│  │  │  ├─ days
│  │  │  │  ├─ dayX.rs
│  │  │  │  ├─ dayY.rs

Will need to take into account differing languages structure requirements (Python flat vs Rust src/?)
