Takes a duration and makes it into string.

The string format is `[0-9]+(ns|us|ms|[smhdwy])`

### Example

String to duration
```rust
use std::convert::TryFrom;
use duration_string::DurationString;
use std::time::Duration;
let d: Duration = DurationString::try_from(String::from("100ms")).unwrap().into();
assert_eq!(d, Duration::from_millis(100));
// Alternatively:
let d: Duration = "100ms".parse::<DurationString>().unwrap().into();
assert_eq!(d, Duration::from_millis(100));
```
duration to string
```rust
use std::convert::TryFrom;
use duration_string::*;
use std::time::Duration;
let d: String = DurationString::from(Duration::from_millis(100)).into();
assert_eq!(d, String::from("100ms"));
```

### Serde support
You can enable serialize/unserialize support by adding the feature `serde_support`
- Add `serde_support` to the dependency
`duration-string = { version = "0.0.1", features = ["serde_support"] }`
- Add derive to struct
```rust
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize)]
struct Foo {
 duration: DurationString
}
```
