Add make:cast command

[jorgemudry]

What does this Pull Request Do?

It adds the make:cast command.

How should this be manually tested?

1. Add the fork to your composer.json file:

    "require": {
        "php": "^7.3|^8.0",
        "laravel/lumen-framework": "^8.0",
        "flipbox/lumen-generator": "dev-feature_add_make_cast_command"
    },
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/jorgemudry/lumen-generator"
        }
    ]

2. Install the package:

$ composer update flipbox/lumen-generator;

3. Use the make:cast command:

$ php artisan make:cast MyCast

4. You should end up with a MyCast.php class in your app/Casts directory looking like this:

<?php

namespace App\Casts;

use Illuminate\Contracts\Database\Eloquent\CastsAttributes;

class MyCast implements CastsAttributes
{
    /**
     * Cast the given value.
     *
     * @param  \Illuminate\Database\Eloquent\Model  $model
     * @param  string  $key
     * @param  mixed  $value
     * @param  array  $attributes
     * @return mixed
     */
    public function get($model, $key, $value, $attributes)
    {
        return $value;
    }

    /**
     * Prepare the given value for storage.
     *
     * @param  \Illuminate\Database\Eloquent\Model  $model
     * @param  string  $key
     * @param  array  $value
     * @param  array  $attributes
     * @return mixed
     */
    public function set($model, $key, $value, $attributes)
    {
        return $value;
    }
}
