package/python-crossbar: drop package

The current package has not recieved an update since Sat Oct 9 2021
33ece2446e and is not python 3.12 compatible.

Furthermore, the current version requires at least 42 new packages worth of
depedencies of which several require patches to be python 3.12 compatible.
As nobody has stepped up to maintain the package and its ever-growing list of
dependencies, along with the other problems, it is time to drop the package.
