Package private and private records cannot be deserialized

[theigl]

Describe the bug
While testing #847 I noticed that package private records cannot be deserialized.

To Reproduce

    static record PackagePrivateRecord(int i, String s) {}
    
    @Test
    void testNonPublicRecords() {
        kryo.register(PackagePrivateRecord.class);

        roundTrip(4, new PackagePrivateRecord(1, "s1"));
    }

This fails with:
