Add electron 'DFCommonAddAmbiguity' to PHYSLITE
This MR simply adds one variable ('DFCommonAddAmbiguity') on the electron container in PHYSLITE used for custom electron-photon rejection. This is possible together with electron.author and electron.ambiguityType (which are already included), but DFCommonAddAmbiguity is still missing on PHYSLITE.
This variable is not affected by systematic variations.
Needed for both Data and MC.
