Add grid system for frames rendering

[Kolozuz]

Description

Currently each frame of the pets animation is manually generated, the idea is to add a grid system so that frames can be generated dynamically, here's an example of what i mean by "grid" (essentially an array of arrays, aka two dimensional array):

# python example
grid = [
  ["","","","","","","","","",""]
  ["","","","","","","","","",""]
  ["","","","","","","","","",""]
  ["","","","","","","","","",""]
  ["","","","","","","","","",""]
  ["","","","","","","","","",""]
]

Acceptance Criteria

• [x] Grid must be dynamic, without fixed values.

// Not like this, notice the fixed grid dimensions
let mut grid:Vec<Vec<&str>> = vec![vec!["."; 12]; 6];
//                                           ^^   ^ grid dimensions

// Instead it should be a function (preferably a object's method), so that the desired grid
// dimensions can be parametrized, something like this:
pub fn new(width:usize, height:usize) -> Vec<Vec<&'static str>>{
    let grid:Vec<Vec<&str>> = vec![vec!["."; width]; height];
    return grid//                            ^^^^^^  ^^^^^^ grid dimensions
}

• [ ] To implement the dynamic grid with pedrito, to make sure it works.

Current

Right now every frame is manually generated (kinda cringe smh :disappointed:)

Notes

Thew way of printing or drawing our grid should be something like this

for row in grid {
    let mut rowstr: String = String::new();
    for cell  in row {
        rowstr += cell;
    }
    println!("{}", rowstr);
}

// 12x6 grid output if every character was a dot
// ............
// ............
// ............
// ............
// ............
// ............

is this still in development? what other issues are there? I mean what was this turn like? (Si, me causo gracia traducir un modismo o coloquialismo, no se. Aunque no se si este correcto.)

Hahah yeah this vuelta is still in developement, in general it's no really too hard to implement, the main reasons why it is taking long are:

• I'm having trouble deciding wether or not implementing the Grid as a class is a good idea, honestly in my opinion it's unnecessarily complex.

  If you want we can review the class approach, i would appreciate your feedback on that.

• Still haven't decided how the animation should work, and want to let that ready before closing the issue, my current idea involves adding a size attribute to the Cat class, then our grid system would have a predetermined position for the parts of the cat that move, like eyes and tail, and according to the Cat's size attribute it will animate it in one way or the other.

For now i think i will just implement the grid system as a function in the utils module and call it a day, so that i can start working on the animation process, which shouldn't take too much time.

Sorry for such long text lmao, i was inspired, feel free to translate it xd
