Expose replication latency via FUSE #253

Similar to the -pos file, it would be useful for applications to be able to track the current latency. We expose latency via the Prometheus metrics so it's just a matter of wiring it up to FUSE.

This was originally spurred by a discussion on HN: https://news.ycombinator.com/item?id=34251743

Should we close this since https://github.com/superfly/litefs/pull/340 merged?
