Import uasyncio

[mishal]

Hello Peter,

first let me thank you for this great repository and docs!

In micropython v 1.22.1 (released Oct 6, 2023) uasyncio becomes asyncio (see: https://github.com/micropython/micropython/releases/tag/v1.21.0) . I do not know what version of micropython should this repo support, but imports across code in this repo imports uasyncio or uses try-catch block which tries to to import uasyncio with fallback to asyncio. The release notes comments this change as: Now, one should just always import the non-u-version and no longer think about u-naming.

It's not a big deal, but may cause some confusion.

Thanks for the report. I have updated the tutorial text, but dealing with the various modules is on my todo list.

I have now removed all references to uasyncio save an intentional one in the tutorial. Thanks for prompting me to do this.
