WIP: Inclusion of muon lines in the HLT1 sequence

This merge request includes the definition of four different lines using muons for the upgrade:

• single_muon: selecting muons with PT > 1.5 GeV and track chi2 < 3.
• single_muon_detached: selecting detached muons with IP > 10 mm, PT > 80 MeV, IPCHI2 > 100 and track chi2 < 3.
• dimuon: selecting combinations of two muons with PT > 400 MeV, track chi2 < 3, mass > 220 MeV and vertex chi2/ndof < 25.
• dimuon_detached: selecting combinations of two detached muons with IP > 0.4 mm, PT > 80 MeV, IPCHI2 > 9, track chi2 < 4, mass > 220 MeV and vertex chi2 < 25.

All tracks are asked to pass the VELO-UT-Muon matching algorithm, but no further muon-ID requirements are applied. The retentions I obtained after running in minimum bias (TestFileDB: MiniBrunel_2018_MinBias_FTv4_MDF) are the following:

• single_muon: (0.2661005 +- 0.00604907)%
• single_muon_detached: (0.6369866 +- 0.00934161)%
• dimuon: (0.06480167 +- 0.00298811)%
• dimuon_detached: (0.1778599 +- 0.00494762)%

I also tested this using KS0 -> mu+ mu- MC (TestFileDB: upgrade-magup-sim10-up01-34112106-xdigi) and the retentions are the following:

• single_muon: (0.6113392 +- 0.0334489)%
• single_muon_detached: ( 1.244775 +- 0.0475771)%
• dimuon: (0.2117591 +- 0.0197257)%
• dimuon_detached: (0.8249397 +- 0.0388136)%

For the moment there is no way to determine TIS and TOS efficiencies, so these numbers are just a global efficiency for this type of event. If this corresponded to the TOS efficiency, it would be within the order of magnitude of the efficiency that we expect for the upgrade.
