Enable pack.writeReverseIndex to true to see the effect of writing
the reverse index in the existing bitmap tests (with and without
lookup table).
Below is the result of performance test. Output format is in
seconds.

Tests 4-15 are without the use of lookup table. The rests are
repeatation of the previous tests but using lookup table.
