Timer facilities for Rust's async story

## Accuracy

Regular timers that do not rely on async event loop tend to be on par with user space timers
like in `tokio`.
If that's not suitable for you you should enable event loop based timers which in most cases
give you the most accurate timers possible on unix platforms (See features.)

## Features

- `tokio1` - Enables event loop based timers using tokio, providing higher resolution timers on unix platforms.
- `c_wrapper` - Uses C shim to create bindings to platform API, which may be more reliable than `libc`.
- `std` - Enables usage of std types (e.g. Error)

## Examples

### Timed

```rust
async fn job() {
}

async fn do_job() {
    let work = unsafe {
        async_timer::Timed::platform_new_unchecked(job(), core::time::Duration::from_secs(1))
    };

    match work.await {
        Ok(_) => println!("I'm done!"),
        //You can retry by polling `expired`
        Err(expired) => println!("Job expired: {}", expired),
    }
}
```

### Interval

```rust
async fn job() {
}

async fn do_a_while() {
    let mut times: u8 = 0;
    let mut interval = async_timer::Interval::platform_new(core::time::Duration::from_secs(1));

    while times < 5 {
        job().await;
        interval.wait().await;
        times += 1;
    }
}
```
