Packing python bools as tw net bools just works

python handles bools more like the ints 0 and 1
and those are exactly the values the
teeworlds network protocol expects

I can totally see this breaking in python4
or a new mypy version

maybe one day a ``get_bool()`` could make sense
also for readability

but for now this should be stable as long as the
tests pass
