in uasyncio implement create_datagram_endpoint: this would make UDP, especially servers, way easier

[ari-s]

the standard python's stdlib's asyncio has create_datagram_endpoint, which essentially allows to act on a received UDP packet / "datagram" in an obvious way (see the udp echo server example).

It would be great if this would be implemented in uasyncio.

Currently something analogous can be done in micropython can be seen here
but it's hard to understand what's going on. Plus it uses asyncio.core._io_queue.queue_read that at least from naming looks internal, and is not documented.

I'd like to make this a feature request issue, but there it says to start a discussion here first, so here's the discussion.
