    ```

    Any parameters can be set:

    __PACKAGE__->load_plugins(
        'Web::CpanelJSON' => {
            unbless_object => \&Object::UnblessWithJSONSpec::unbless_with_json_spec,
        }
    );

    ...

    package Some::Object {
        use Mouse;

        has message => (
            is => 'ro',
        );
    }

    my $object = Some::Object->new(message => 'HELLO');

        'Web::CpanelJSON' => { status_code_field => 'status' }
    );

    ...

    $c->render_json({ status => 200, message => 'ok' })
    # send response header 'X-API-Status: 200'
