Installing async_button warning -> adafruit_asyncio is not a known package

[javigit]

I believe the correct package name is asyncio instead of adafruit_asyncio, which I found here https://github.com/adafruit/Adafruit_CircuitPython_asyncio
-- circup install asyncio

This is actually a bug in circup. I have created a pull request (adafruit/circup#167) to fix it. I am therefore closing this issue - please reopen if this behaviour continues with an updated version of circup
