Add Queue and other asyncio features from MicroPython unofficial version of asyncio

[dhalbert]

https://github.com/peterhinch/micropython-async contains a number of additions to MicroPython's asyncio that have not yet made it into the https://github.com/micropython/micropython repo. Consider adding those features which are compatible with the CPython library, such as:

• Queue

Any status update on this?
Even if it's just a "won't do", but even better withn an explanation on the "why not" (?) :)

[dhalbert]

It's not a "won't do" :) -- we are looking at a bunch of things around asyncio, and haven't yet decided on the next steps. See adafruit/circuitpython#7554 for eaxmple.

Another +1 for this. I just recently got bit by Queue being available on rpi with blinka but not the rp2040 board.

  File "asyncio/__init__.py", line 42, in __getattr__
AttributeError: Queue

As I wanted to fiddle with asyncio and needed Queues and Semaphores ...

I simply copied queue.py and semaphore.py into /lib/asyncio/ these 2 files from
https://github.com/peterhinch/micropython-async/blob/master/v3/primitives/

and import the modules this way:
import asyncio
from asyncio.queue import Queue
from asyncio.semaphores import Semaphore

So far, So good ... not an official "Pull-request" as I am not mastering the deep core of asyncio BUT it worked for me

@ericbaril72 I assume you've used the python files for the asyncio library on your board/drive? Not the .mpy files? Thanks!

@dhalbert any updates? Thanks!
