Add 2 LUTs for HI use

The first is for the HI centrality trigger and is already populated with a first draft of the LUT contents. The second is for the future use of the Q2 trigger and is not populated yet.

This also involved changes to the conversion to the legacy dataformats that were worked out with the HI L1 menu definition.

@mulhearn, is this the right way to add a LUT? I had to edit some things which probably affect Stage2.

@icali and @ginnocen, does this match what we agreed with the L1 HI menu?
