Install fails with recent python/pip versions

[hmeine]

I am using python 3.12.10 and pip 25.0.1, and for me pip install fails with this error:

  × Getting requirements to build wheel did not run successfully.

The problem seem to be that setup.py imports tr064 in order to be able to set version=tr064.__version__. (Also note that the problem is independent of whether one has lxml installed or not; apparently the wheel building process uses an isolated environment.)
