Use async module to speed up pad processing #6

We could also batch the pad IDs into groups and then use the core async library to run them asynchronously. This could drastically speed things up if you have a bunch of cores. Might need some investigation to realise first though.

Combined with #5, we could really have a faster feedback loop.

loop = asyncio.get_event_loop()

tasks = []
url = "http://localhost:8080/{}"

for i in range(5):
    task = asyncio.ensure_future(hello(url.format(i)))
    tasks.append(task)

loop.run_until_complete(asyncio.wait(tasks))

You could also check what I did here with the multiprocessing library to use different threads for doing HTTP requests.

Comes down to the same I guess..

OK, that's in. I used the trio async library and asks HTTP client.
