daq eff improvements
Basically, this version returns the same results as the older eff_daq_splunk app, but with better stop info logic plus all the other improvements.
Changes:
- detector list manipulation at output level to change all blank spaces in their names into underscores
- added "Eff=" field for directly computed LB efficiency based on busy times from all sources
- edge time interval stop info correctly computed
- if requested time interval started or ended in non-running FSM state, the app would not take it into account for stop info computation
- seen some seg violations during no-run&no-beam intervals so added some protections
