ElectronPhotonSelectorTools: Add new photon ID menus
Adds new photon ID menus (medium/tight), see ATLASG-2708 for more details.
DerivationFrameworkEGamma: Add medium photon ID -> ey group would like to have a feedback on the new working point so it would be good to include it in the new PHYS/PHYSLITE. This will add extra selection flag to PHYS/PHYSLITE.
First need confirmation from ey group @dduda @kliu @ludovica @kristin then I will remove the draft.
Also @gmarchio can you x-check changes to the derivations? Thanks
