Adding the mc23c profile provided by data preparation, and including that instead of the placeholder flat profile. This will allow to run presampling with the actual profile.
I have also increased the maximum number of pileup events for mc23c to 90.5, since that's where the maximum value we have - will need to load more minimum bias events in presampling. And I decreased the mc23a number down to 61.5 so that we don't load more events than needed for mc23a.
