Tiny Gleam dependency injection. Make IO functions unit tests friendly.

```sh

gleam add glency

```

```gleam

import glency

type Cat {

  Cat(name: String, age: Int)

}

pub fn main() {

  glency.init_di() // Firstly init DI container on application startup

  {

    // Mock implementation of `fetch_cat`

    use <- glency.with_di(fetch_cat, fn(_cat_id) { Cat("Barsik", 7) })

    fetch_cat(1) // will avoid IO, returns Barsik cat

  }

}

pub fn fetch_cat(cat_id: Int) {

  use <- glency.di(fetch_cat, #(cat_id)) // Make IO function DI friendly

  // Here production IO implementation of function

}

```
