Release 0.1.2-alpha dependency to async-upnp-client breaks integration

[B5r1oJ0A9G]

In release of 0.1.2a all UPnP calls are implemented by async-upnp-client and the previously used module upnpclient was removed. This change was dependent on some pull requests to async-upnp-client which have finally been released with version 0.15.0 of async-upnp-client.
As there is a general version pinning in HA for a selection modules, including async-upnp-client, this requirement from teufel_raumfeld is currently prevented by HA to be met and finally leads to issues resp. error messages like the following ones:

Currently identified work-arounds (In recommended order):

• Roll back to 696ac9b or to release 0.1.1a.
• Manual modification of HA software package constraints. See: Bump async-upnp-client to 0.15.0 home-assistant/core#47885.
• Check out https://github.com/B5r1oJ0A9G/teufel_raumfeld/tree/dev-enforced-requirements, which implements a configuration option during integration addition to enforce the requirement needed by teufel_raumfeld.
