fixate socketio and engineio

[Reimar Bauer]

Until anaconda default channel has not an update we have to fixate both packages in the mss-feedstock

python-socketio 4.4.0 py_0 conda-forge

python-engineio 3.11.2 py_0 conda-forge

‌

I will solve this also 1.9.2 by a new build

Merged in ReimarBauer/mss/stable (pull request #820)

fixated python-socketio added missing defusedxml, fixes #546
