WIP: Synchronize std and kronos macros for mCBM2020 event building, refs #1827

The macros for the mCBM 2020 event builder based on time windows are slightly diverged:

• Examples for some parameters were missing in the kronos version of the macro (but still consistent due to default values)
• The PSD upper limit of the time window was up to date only in the kronos version

No urgency as the kronos version was in a state were the common files could be generated.
