cbor: STRINGREF String reference outside of a namespace

[ajafff]

Tested with 3.0.4 and 3.1.0

Minimal repro:

import static org.assertj.core.api.Assertions.assertThat;

import java.util.List;
import org.junit.jupiter.api.Test;
import tools.jackson.dataformat.cbor.CBORMapper;
import tools.jackson.dataformat.cbor.CBORWriteFeature;

public class CborMapperTest {

    private final CBORMapper mapper = CBORMapper.builder().enable(CBORWriteFeature.STRINGREF).build();

    @Test
    public void test() {
        var original = List.of("foo", "foo");
        var serialized = this.mapper.writeValueAsBytes(original);
        var deserialized = this.mapper.readValue(serialized, List.class);
        assertThat(deserialized).isEqualTo(original);
    }
}

Produces the following error:

String reference outside of a namespace
 at [Source: (byte[])[8 bytes]; byte offset: #8]
tools.jackson.core.exc.StreamReadException: String reference outside of a namespace

Not sure if this is an issue in the Parser or Writer, but either way, I would expect it to round-trip without an error.
