Suggestion: add human readable toString method

[8ctopus]

When the url contains unicode, toString(), returns an url encoded string which is not human readable

$reference = Url::parse("https://test.com");
$url = $reference->resolve('/デジカ/');

echo $url->toString(); // https://test.com/%E3%83%87%E3%82%B8%E3%82%AB/

I suggest to add a new method toPrettyString() which simply returns the url decoded string.

    public function toPrettyString(): string
    {
        return urldecode($this->url);
    }
