Function groupByProp

groupByProp<K, V>(values: Iterable<V>, keySelector: ((item: V) => K), propSet: Iterable<K>): Record<K, V[]>
Example
```
const { num1, num2, num3 } = groupByProp(
  [1, 2, 100, 200],
  (num) => `num` + num.toString().length,
  ['num1', 'num2', 'num3']
);
// num1 → [1, 2]
// num2 → []
// num3 → [100, 200]
```
