Getters needed for ignored properties

I'm wondering that I have to write getters for ignored properties. Here's an working example:

```java
import java.io.IOException;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
import com.fasterxml.jackson.databind.MappingIterator;
import com.fasterxml.jackson.dataformat.csv.CsvMapper;
import com.fasterxml.jackson.dataformat.csv.CsvSchema;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;

@JsonPropertyOrder({
"text",
"ignored",
"number"
})
@JsonIgnoreProperties(ignoreUnknown = true)
public class Example {

private String text;
private Integer number;

@JsonCreator()
public Example(String text, Integer number) {
this.text = text;
this.number = number;
}

public String getText() {
return text;
}

public Integer getNumber() {
return number;
}

// jackson needed getter
public Object getIgnored() {
return null;
}

public static void main(String[] args) throws IOException {

CsvMapper csvMapper = new CsvMapper();
csvMapper.registerModule(new ParameterNamesModule());
CsvSchema csvSchema = csvMapper.schemaFor(Example.class);

String value = "foo, ignoredValue, 123";

MappingIterator iterator = csvMapper.readerFor(Example.class)
.with(csvSchema)
.readValues(value);

var nextValue = iterator.next();

System.out.println(nextValue.getText() + ", " + nextValue.getNumber());

}
}
```

If you *delete* the getter `getIgnored()`, the following exception will be thrown:

```
Exception in thread "main" com.fasterxml.jackson.databind.RuntimeJsonMappingException: Cannot deserialize value of type `java.lang.Integer` from String "ignoredValue": not a valid `java.lang.Integer` value

Is this expected behavior? Is there something I can do to omit writing these getters?

What's also interesting: You got a different exception when the ignored column is the last:

```java
import java.io.IOException;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
import com.fasterxml.jackson.databind.MappingIterator;
import com.fasterxml.jackson.dataformat.csv.CsvMapper;
import com.fasterxml.jackson.dataformat.csv.CsvSchema;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;

@JsonPropertyOrder({
"text",
"number",
"ignored"
})
@JsonIgnoreProperties(ignoreUnknown = true)
public class Example2 {

private String text;
private Integer number;

@JsonCreator()
public Example2(String text, Integer number) {
this.text = text;
this.number = number;
}

public String getText() {
return text;
}

public Integer getNumber() {
return number;
}

// jackson needed getter
public Object getIgnored() {
return null;
}

public static void main(String[] args) throws IOException {

CsvMapper csvMapper = new CsvMapper();
csvMapper.registerModule(new ParameterNamesModule());
CsvSchema csvSchema = csvMapper.schemaFor(Example2.class);

String value = "foo, 123, ignoredValue";

MappingIterator iterator = csvMapper.readerFor(Example2.class)
.with(csvSchema)
.readValues(value);

var nextValue = iterator.next();

System.out.println(nextValue.getText() + ", " + nextValue.getNumber());
}
}
```

If you now *delete* the getter `getIgnored()`, the following exception will be thrown:

```
