ctaus in topo
Implementation of the combined taus multiplicity in the L1Topo simulation. Basic design discussed here https://indico.cern.ch/event/1079697/contributions/4541419/attachments/2315137/3940824/cTAU_FirmwareAlgoProposal.pdf
The isolation working points need to combine jtau and etau; for lack of a better place to define these they are coded at the moment in the multiplicity algorithm itself. Cuts are applied in same way as we do for all other multiplicities.
