Description
I want to store usize in a gauge metric without conveting it to u64, but Atomic trait is not implemented for usize:
https://docs.rs/prometheus-client/0.22.2/prometheus_client/metrics/gauge/trait.Atomic.html
Because of this Gauge::<usize, AtomicUsize>::default(). Is there any reason for not supporting it? Would it require too high MSRV?

Research direction
Start with the Atomic trait documentation linked in the issue and the Gauge::<usize, AtomicUsize>::default() usage described there. Check the project's MSRV and existing Atomic implementations to determine whether usize can be supported. Done means usize can be stored in a gauge without conversion and the relevant checks pass.
