Missing __isset magic method / Compatability Issues with Laravel Collections

[Cbrad24]

The base class for an RR record seems to implement the magic method __get but not __isset as seen here:

netdns2/src/NetDNS2/RR.php

Lines 211 to 219 in df04947

	public function __get(string $_name): mixed
	{
	if (property_exists(get_called_class(), $_name) == false)
	{
	throw new \NetDNS2\Exception(sprintf('undefined property: %s', $_name), \NetDNS2\ENUM\Error::INT_PARSE_ERROR);
	}
	return $this->$_name;
	}

This caused some compatibility issues with Laravel Collections due to helper methods (used internally in collections) checking if the value was set before retrieveing it as below.

I have found a workaround by using a callback and invoking the property directly but the following code does not work due to the missing function:

$resolver = new Resolver([
    'nameservers' => [
        '1.1.1.1',
        '8.8.8.8',
    ],
]);

$response = $resolver->query('github.com', 'MX');

// This does not work
return collect($response->answer)
    ->sortBy('preference');

// Using a callback works
return collect($response->answer)
    ->sortBy(fn ($item) => $item->preference)

I know it's not specifically a NetDNS issue however I don't see a reason we couldn't implement the __isset magic method.
