It seems like $object can also be of type array; however, Rafrsr\LibArray2Object\Array2Object::parseValue() does only seem to accept object, maybe add an additional type check?

The expression self::$parsers of type array|object<Rafrsr\LibArray2Object\Parser\ValueParserInterface> is not guaranteed to be traversable. How about adding an additional type check?
