[Buildroot] [PATCH 2/2] package/python-opcua-asyncio : new package

[Jugurtha BELKALEM]

opcua-asyncio is an asyncio-based asynchronous OPC UA client
based on python-opcua, removing hacks for support of
python < 3.6. 
Asynchronous programming allows for simpler code (e.g. less need
for locks) and potentially performance gains.
