go_* metrics do not use VictoriaMetrics histogram

I'm using export process metrics as described in the example.
```
metrics.WritePrometheus(w, true)
```
and the timing metrics use a Prometheus type histogram with `le` instead of a VM type histogram with `vmrange`.
```
go_sched_latencies_seconds_bucket{le="0"} 0
```
Why is that? Do you plan to support the ability to provide go_* histogram metrics using the VM way?
