Add the ability to replicate Laravel models to other models.

CanBeReplicated.php

<?php

use Illuminate\Support\Arr;

trait CanBeReplicated
{
    public function replicateTo(string $model, array $with = null, array $except = null)
    {
        $defaults = [
            $this->getKeyName(),
            $this->getCreatedAtColumn(),
            $this->getUpdatedAtColumn(),
        ];

        $attributes = Arr::except(
            $this->attributes, $except ? array_unique(array_merge($except, $defaults)) : $defaults
        );

        $attributes = array_merge($attributes, $with ?? []);

        return tap(new $model, function ($instance) use ($attributes) {
            $instance->setRawAttributes($attributes);

            $instance->setRelations($this->relations);

            $instance->fireModelEvent('replicating', false);
        });
    }
}

Wow, 💯

Yesterday I had the same problem. I came up with something similar, but ended using two different models (the new one extending the old one).
