This is because Debian's python-typing is now 3.6.1, so that requirement
can't be satisfied. I am wondering why this limitation to versions < 3.6
is required, maybe you could shed some light on this. It builds fine
with 3.6.1 but since there don't seem to be tests it's difficult to
check whether that indeed works at runtime or not...

I also added a missing build-dependency on python-avro, which stopped
the build before. The FTBFS should be fixed now.

I have pushed my changes to git and would be happy to get some comments.

Many thanks
Sascha
