I just added mos-cq Conversational Quality

I will test it a little bit more, but I have used similar code before

oh wow!
congratulations!!
I'll try to use it!

In the case of voip_patrol, it seems what is missing it taking the discarded packet from the JBM they are in frames so a little conversion is needed.
But we have the delay impairment assuming no echo.
It think is it good to stick with the formula they use, this way we can even add more impairments when they become available.
Burst density in RTCP-RX for example, SNR, echo delay.

Not sure why they ended up with such complicated formula , I found this study yesterday, it seems interesting

The least we can say is that they put some time and effort in trying to solve this challenge efficiently :)

one more note, I did not test this enough yet. (Even if I did use and test similar code before).
