Cannot use PrometheusMetricsBuilder with default prometheus registry and lazy static

[artefom]

PrometheusMetricsBuilder consumes Registry not allowing to pass default prometheus registry. This prevents usage of very convinient lazy static metrics from prometheus package

// This will register to prometheus::default_registry()
lazy_static! {
    static ref HIGH_FIVE_COUNTER: IntCounter =
        register_int_counter!("highfives", "Number of high fives received").unwrap();
}

// ...

let prometheus = PrometheusMetricsBuilder::new("api")
    .endpoint("/metrics")
    .registry(prometheus::default_registry()) // <<<<<<<<<<<<<<<<<<<<<< ERROR
    .build()
    .map_err(|e| RunServiceError::Prometheus(e.to_string()))?;

Though, from the first glance it should be perfectly possible to accept registry by reference instead
