PF clustering with time information: additions and fixes

- Adds the possibility to use a parametric resolution for the ECAL rec-hit time in the different clustering steps; updates parameters in the cluster selection
- Additional options for using the time information in the PF clustering
- Fixes an issue that prevented PFClusters in the EE from passing the time selection

Note: The clustering that makes use of the rec-hit time information is still disabled by default.
