Unhandled aiohttp exception if receiver refuses connection

@JPHutchins I tried the pyavreceiver library, but I get an exception when executing the following code from command line on windows pc:

ping 192.168.1.IP --> Replay OK
python3 -m asyncio
import asyncio
from pyavreceiver import factory
d = await factory("192.168.1.IP")
I get this exception:
aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host 192.168.1.IP:60006 ssl:default [The remote computer refused the network connection]
I don't think port 60006 is open on my Marantz SR5008, also note that my Marantz SR5008 does not support Heos, so it may be missing the required API for this...
