Async iterator methods and async methods for option and result.

How to use with Cargo:

[dependencies]
async-iter-ext = "0.3.0"

How to use in your crate:

use async_iter_ext::AsyncIterTools;

Simple map_async example

use async_iter_ext::{AsyncIterTools, AsyncIterator};
use async_std::task::sleep;
use std::time::Duration;

#[async_std::main]
async fn main() {
  let items = [1, 2, 3, 4];

  let mapped_items_vec = items
    .iter()
    .map_async(|item| async move {
      sleep(Duration::from_millis(100)).await;
      item * 2
    })
    .async_collect::<Vec<_>>()
    .await;

  assert_eq!(mapped_items_vec.len(), items.len());
  assert_eq!(mapped_items_vec, vec![2, 4, 6, 8]);  
}
