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} from 'path-exists';
import pLocate from 'p-locate';

const files = [
	'unicorn.png',
	'rainbow.png', // Only this one actually exists on disk
	'pony.png'

const foundPath = await pLocate(files, file => pathExists(file));

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