/**
Get the first fulfilled promise that satisfies the provided testing function.
@param input - An iterable of promises/values to test.
@param tester - This function will receive resolved values from `input` and is expected to return a `Promise<boolean>` or `boolean`.
@returns A `Promise` that is fulfilled when `tester` resolves to `true` or the iterable is done, or rejects if any of the promises reject. The fulfilled value is the current iterable value or `undefined` if `tester` never resolved to `true`.
@example
```
import pathExists = require('path-exists');
import pLocate = require('p-locate');
const files = [
'unicorn.png',
'rainbow.png', // Only this one actually exists on disk
'pony.png'
];

console.log(foundPath);
//=> 'rainbow'
