Wait for a specified number of promises to be fulfilled.
@param values - An `Iterable` collection of promises/values to wait for. If you pass in cancelable promises, specifically promises with a `.cancel()` method, that method will be called for the promises that are still unfulfilled when the returned `Promise` is either fulfilled or rejected.
@returns A [cancelable `Promise`](https://github.com/sindresorhus/p-cancelable) that is fulfilled when `count` promises from `input` are fulfilled. The fulfilled value is an `Array` of the values from the `input` promises in the order they were fulfilled. If it becomes impossible to satisfy `count`, for example, too many promises rejected, it will reject with an [`AggregateError`](https://github.com/sindresorhus/aggregate-error) error.
@example
```
import got = require('got');
import pSome = require('p-some');
(async () => {
const input = [
got.head('github.com').then(() => 'github'),
got.head('google.com').then(() => 'google'),
got.head('twitter.com').then(() => 'twitter'),
got.head('medium.com').then(() => 'medium')

console.log(first, second);
//=> 'google twitter'
