Configurable to exclude the loading of the full geometru for the DCA calculation. With no propagation as in the old version of the task allows to reduce the memory consumption of a factor ~20 (from ~450MB to ~20MB). The test produced is saved in this repository: https://cernbox.cern.ch/files/spaces/eos/user/l/lmichele/FwdTrackExtension_test
THe performance metrics can be loaded here to see the impact of the option.
