[Common] Allow stopping before reaching partonic level in RecoDecay::getMother

[fchinu]

Until now, the getMother function would search up the full partonic shower to search for a mother, if depthMax was not set. With this PR I have added a new parameter to stop the search once the partonic level is reached.
