To process a data set a given concurrency level.

await roll(items, (item) => { /* async processor of item */ }, concurrencyLevel);

To make only one async call for multiple incoming request and cache the output.

const hub = new Hub(()=> { /* to fetch the data */ }, cacheTimeout);
const data = await hub.get();

Here the callback function will be called only once even hub.get() is called multiple times.
