## ascii-art

### Objectives

Ascii-art is a program which consists in receiving a `string` as an argument and outputting the `string` in a graphic representation using ASCII. Time to write big.

What we mean by a graphic representation using ASCII, is to write the `string` received using ASCII characters, as you can see in the example below:

```````````console
@@@@@@BB@@@@``^^``^^``@@BB$$@@BB$$
@@%%$$$$^^^^WW&&8888&&^^""BBBB@@@@
@@@@@@""WW8888&&WW888888WW``@@@@$$
BB$$``&&&&WWWW8888&&&&8888&&``@@@@
$$``&&WW88&&88&&&&8888&&88WW88``$$

```````````

- This project should handle an input with numbers, letters, spaces, special characters and `\n`.
- Take a look at the ASCII manual.

### Instructions

- Your project must be written in **Go**.
- The code must respect the [**good practices**](../good-practices/README.md).
- It is recommended that the code present a **test file**.

- Some **banner** files with a specific graphical template representation using ASCII will be given. The files are formatted in a way that is not necessary to change them.

  - [shadow](shadow.txt)
  - [standard](standard.txt)
  - [thinkertoy](thinkertoy.txt)

### Banner Format

- Each character has a height of 8 lines.
- Characters are separated by a new line `\n`.
- Here is an example of ' ', '!' and '"'(one dot represents one space) :

```console

......
......
......
......
......
......
......
......

._..
|.|.
|.|.
|.|.
|_|.
(_).
....
....

._._..
(.|.).
.V.V..
......
......
......
......
......

```

### Usage

```console
student$ go run . "" | cat -e
$
student$ go run . "\n" | cat -e
$
$
student$ go run . "Hello\n" | cat -e
