Support configurable NamingStrategy.ExampleName

For example:

```java
public final class MyJUnitXmlFormatter implements ConcurrentEventListener {

    private final MessagesToJunitXmlWriter writer;

    public JUnitFormatter(OutputStream out) {
        this.writer = new MessagesToJunitXmlWriter(NamingStrategy.ExampleName.PICKLE, out);
    }

    @OverRide
    public void setEventPublisher(EventPublisher publisher) {
        publisher.registerHandlerFor(Envelope.class, this::write);
    }

    private void write(Envelope event) {
        try {
            writer.write(event);
        } catch (IOException e) {
            throw new IllegalStateException(e);
        }

        if (event.getTestRunFinished().isPresent()) {
            try {
                writer.close();
            } catch (IOException e) {
                throw new IllegalStateException(e);
            }
        }
    }

}
```

Note: Cucumber-JVM at present doesn't allow much configuration of plugins.
To take advantage of this new option, the class above must be copied. And
can be used in Cucumber-JVM with
`cucumber.plugin=com.example.MyJUnitXmlFormatter:target/report.xml`.

Fixes: #27
