Scouting Phase 2 - Inclusion of PF and TTracks

[caroll-costa]

• Introduction of new Data Format RecMeson corresponding to the meson candidates
• Introduction of ScPhase2RecMesonAll module, which reconstructs the mesons from PF candidates
• Introduction of ScPhase2RecIsoTkEm module, which computes the isolation of TkEm
• Adapt the analyses modules to consume the orbit collections of reconstructed mesons and isolated TkEm
• Introduction of new Tracker Tracks - both the Data Format L1ScoutingTTrack and corresponding Unpacker
• Introduction of ScPhase2TkRecMesonAll module, which reconstructs the mesons from TTracks

Don't take it bad, but there's a bit of cleanup needed before this can be merged.
