chat/py-matrix-nio: import py39-matrix-nio-0.18.7

nio is a multilayered Matrix client library. The underlying base layer
doesn't do any network IO on its own, but on top of that is a full
fledged batteries-included asyncio layer using aiohttp. File IO is only
done if you enable end-to-end encryption (E2EE).
