MuonPadsToMuonClusters spend most of the time in the dd4hep::printout function

Looking at a flamegraph on 2025 data, the class MuonPadToMuonClusters spends a lot of time in the dd4hep::printout function, despite not printing anything (and despite it not being needed for running). This amounts to a bit less than 1% of the full HLT2 sequence.
