Wrong extraction of dlh5 muon files
In the muon_extractor from offlineh5 files to dlh5 files, the energy is calculated wrong.

Right now the energy is calculated as the sum of energy entries for the blob. This is made of the rimary and all secondaries. To only count the primary, a check for minimum number of hits is used. This however also effect some primaries. Better would be:
energy = blob["McTracks"].energy[0]
