Installation documentation

I struggled quite a bit to get the Tapo-P100 plugin working in an environment with python 3.9. The instruction as provided did not work for me and I need to do following:

• When the Installation of the @petretiandrea plugp100 was done as non-root user, domoticz was not able the find the module locally. When i installed with 'sudo pip install plugp100', domoticz had no problem find the module
• The 3rd bullet of 'How to install the Python v3.8 / v3.9 version' for plugp100-3.9 says download the ZIP file, and then follows a link the Domotiz Plugin. What you mean here is obviously the zip of the plugp100-3.9 archive instead. (took me some time to realise that)
• Having done a root level install of plup100, I needed to copy the plugp-3.9 as 'sudo cp -a plugp100/ /usr/local/lib/python3.9/dist-packages/' of course.
• For the plugin itself, domoticz could be no means locate the p100.py file, At some point I had maybe 5 or 6 copies of it in all possible paths for my shell. In the end I copied the file to my /home/pi/bin directory and modified the plugin hardcoded to that location, before domoticz was able to locate the file.

The issues I encountered may be related to my specific domoticz installation.

Getting things working, I see that any command to the plug takes extremely long (10-20 seconds).
When a command is entered manually with p100py, I see following on sterr:

Default protocol not working, fallback to KLAP ;)
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0xb572da30>

Is it possible that the delay is cause by the attempt to use the "Default" protocol?
If so, it could be worth to try configuring "KLAP" as default. If such a configuration would be possible in the plugin in or the p100.py script.
