Lookup table analysis takes an excessive long time when using ROOT6 #146

(reported by Sonal)

Lookup table analysis takes an excessive long time when using ROOT6. The analysis runs as usual, but the last step before exiting takes 20x or longer than before.

Related to change in how TFile::Close() works for root 6.

Changed for table reading mode following https://root-forum.cern.ch/t/long-time-to-close-root-file-with-o-500k-histograms/44229 insrc/VTableLookup.cpp
