* make port mapping optional
* dependencies + improvements
* Added bytes and packets sensors from IGD
* flake8 check
* new sensor with upnp counters
* checks
* whitespaces in blank line
* requirements update
* added sensor.upnp to .coveragerc
* downgrade miniupnpc
Latest version of miniupnpc is 2.0, but pypi only has 1.9
Fortunately it is enough
* revert to non async
miniupnpc will do network calls, so this component can’t be moved to
coroutine
* hof hof
forgot to remove import ot asyncio
