Qcli fixes

[dericed]

a workaround for bavc/qctools#842 #853 and a few other fixes

I just gave this a test and it seems to work for non-concurrent qctools report generation, but concurrent report generation still crashes with a pipe/segmentation fault error. This happens for both 4 channel and 2 channel captures on my end. (Testing this on macOS right now as I don't have my linux machine handy at the moment). See below for relevant terminal output:
