PHP 8.1: offset* signature

[thekid]

With recent PHP 8.1 builds, the following notice occurs:

Return type of util\Bytes::offsetUnset($offset) should either be compatible with ArrayAccess::offsetUnset(mixed $offset): void, or the #[ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

This was suggested in https://wiki.php.net/rfc/internal_method_return_types and introduced in php/php-src#7251

• Adding void as a return type will break backwards compatibility with PHP 7.0
• Adding mixed as type will break backwards compatibility with all PHP 7 versions

For the moment, adding #[ReturnTypeWillChange] seems like the way to go.
