    keyword=repaired online DT calc to inclu T6

    I fixed "datamon" and "halla_scaler_process.tcl" for Left-HRS to
    account for correlations between T3 and T6 to estimate the deadtime.
    It's assumed they are 100% correlated (btw, it's also assumed every
    T5 is a T1 and a T3, but that doesn't matter much now).

    Offline, it is easy to compute deadtime for each trigger (but someone
    should try it to make sure everything works); the issue is we don't
    know -- online -- how much of each trigger is accepted. So we have
    to estimate the correlations.

    The DAQ is down at the moment (someone even rebooted adaql2 [why?])
    so I didn't complete final checks. Let me know if its not ok.
