aggregate-async-iterator

Aggregates several async iterators into one (zip)

usage

``js
import { aggregateRoundRobin, aggregateFifo } from "aggregate-async-iterator";

async function* sequence(name, time = 100, num = 10) {
for (let i = 0; i < num; i += 1) {
yield new Promise(resolve => setTimeout(resolve(name + i), time));
}
}

console.log("RR:");

for await (const r of aggregateRoundRobin([
sequence("A", 100, 3),
sequence("B", 35, 5)
])) {
console.log(r);
}

console.log("FIFO:");

for await (const r of aggregateFifo([
sequence("A", 100, 3),
sequence("B", 35, 5)
])) {
console.log(r);
}
`

Prints interleaved sequences
