Go errgroup.Group for starlark. Allows a starlark thread to spawn go routines.

Each go routine can be optionally pooled and rate limited.

Arguments to go are frozen. Wait returns a tuple of sorted values in order of 

calling. Calls are lazy evaluated and only executed when `wait()` is called.

```python

def square(x):

    return x*x

def square_all(vs):

    # Create a group of 10 go routines, limited every 10ms with a burst of 10.

    g = group(n = 10, every = "10ms", burst = 10)

    for i in vs:

        g.go(square, i)  # args[1:] and kwargs passed to arg[0]

    return g.wait()

print(square_all(range(10)))  # prints: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

```
