1209: Time: Add from_hz function for Duration. r=Dirbaio a=CBJamo

I found myself doing things like this

```rust
    let rate_us = 1_000_000 / rate_hz;
    let mut ticker = Ticker::every(Duration::from_micros(rate_us));
```

Several times, and figured it was worth adding a little convenience function to handle that. This also makes the calculation const, which is a nice little upside. The compiler might have been doing that already, but this makes sure. 

Speaking of const, would it be better to give hz as a float? Obviously we'd want to avoid that at runtime since many targets don't have a fpu, but if it's at compile time that doesn't matter and a float may be more ergonomic.
