Add reference checking test that runs reconstruction and selection
This MR introduces a reference checking test that runs reconstruction and (ThOr) hlt2 selections. A set of generic lines (also included by this MR) is used in the test.
The Size of compressed data
counter from HltPackedDataWriter
has been included in the knows_fluctuating_counters
list since it changes between runs (see LHCb#151 (closed)).
