matrix-client library outdated

[Markus-Be]

matrix-client is outdated and the Maintainer recommends using matrix-nio

We strongly recommend using the matrix-nio library rather than this sdk. It is both more featureful and more actively maintained.

This sdk is currently lightly maintained without any person ultimately responsible for the project. Pull-requests may be reviewed, but no new-features or bug-fixes are being actively developed. For more info or to volunteer to help, please see matrix-org/matrix-python-sdk#279 or come chat in #matrix-python-sdk:matrix.org.
