Support tracking progress of async tasks

[danielgafni]

How would you improve Rich?

Add support to the following:

async for item in track(items):
    ... 

Currently this code fails with:

TypeError: 'async for' requires an object with __aiter__ method, got generator

need async support too, asyncio is where streams mostly used.

I've used rich progressbar via tqdm.rich so far:

• https://github.com/Taxel/PlexTraktSync/blob/bacaba1ad6c068098e5efa0e5db369ca1f0160c3/plextraktsync/factory.py#L123-L144

tqdm has async wrapper, but sadly no without rich:

• https://github.com/glensc/PlexTraktSync/blob/e014c5bed1c122b8f58331bc3f28d8e3445dc32c/plextraktsync/factory.py#L120

perhaps both could be copyed to rich and have support, because tqdm doesn't get much activity in their repo:

• Fix: Add display() call to close() in rich module tqdm/tqdm#1395

No plans to work on this, but I would accept a PR.

I hope we solved your problem.
