Entity cast-on-fill

Come to think of it, though, and a safer way to do it without modifying any code is simply to provide a setX() method that will cast it automatically on the way in.

That would work but I guess what I'm after is a way to normalize data types in bulk. That approach would require a `setX()` method for every attribute and would duplicate the casts we have defined for the way out. For the moment I've written my own extension to `toRawArray()` like I outlined above.

PHP Code:

    /**
     * Force raw array output through casts.
     *
     * @param boolean $onlyChanged
     *
     * @return array
     */
    public function toRawArray(bool $onlyChanged = false): array
    {
        $array = parent::toRawArray($onlyChanged);
        
        if (empty($this->casts))
        {
            return $array;
        }

        // Check each key for a cast
        foreach ($array as $key => $value)
        {
            if (! empty($this->casts[$key]))
            {
                $array[$key] = $this->castAs($value, $this->casts[$key]);
            }
        }

        return $array;
    }
