Extends Aigle.parallel functionality

[suguru03]

I'm thinking to extend Aigle.parallel functionality as below,

(async () => {
  const array1 = await Aigle.parallel([
    (async () => 1)(),
    (async () => 2)(),
    (async () => 3)(),
  ]);
  console.log(array1); // [1, 2, 3]
  const array2 = await Aigle.parallel([
    async () => 1,
    async () => 2,
    async () => 3,
  ]);
  console.log(array2); // [[AsyncFunction], [AsyncFunction], [AsyncFunction]]
})();

// ↓

(async () => {
  const array3 = await Aigle.parallel([
    async () => 1,
    async () => 2,
    async () => 3,
  ]);
  console.log(array3); // [1, 2, 3]
})();

Also, I'll add Aigle.series and Aigle.parallelLimit which are smilar to async.series and async.parallelLimit.
