## Queue device

The queue device can be used to desynchronize processing between one or several tasks that produce
data and a task that consumes queued data.

`import { queue } from 'f-streams'`

-   `q = queue(options)`  
    creates a queue.  
    The queue has two properties:  
    `q.reader`: a reader from which you can read the data which has been queued.  
    `q.writer`: a writer to which you can write data.  
    You can also interact with the queue with the following non-streaming API:  
    `data = q.get()` gets the next item from the queue.  
    `ok = q.put(data)` adds an item to the queue (synchronously).  
    You can pass a `max` option through the `options` parameter when creating the queue.
    If you pass this option, `q.put(data)` will return true if the data has been queued and false if
    the data has been discarded because the queue is full.
    Note that `q.writer will not discard the data but instead will wait for the queue to become available.
