Function asPromise

asPromise<V>(valueToWrap): (() => Promise<V | undefined>)
Treats the chain/generator as a promise
```
const ticker = asPromise(tick({ interval: 1000 }));
const x = await ticker(); //  Waits for 1000ms before giving a value
```
This will only ever return one value. To return multiple values, it's necessary to call asPromise and await the result in a loop.
