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" (?) :)

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.
