Add run 2 data and MC20 samples for ttHH package
This MR adds some of the samples used for mc20 ttHH HH->4b and HH->SSML analysis.
Some still need to be added, mostly not nominal samples:
ttW_EWK_Sh2210, mc20e_ttW_aMcAtNloPy8EG, ttW_MGPy8EG_EWttWsm, mc20e_ttW_aMCPy8EG_FxFx01jNLO, ttll, ttll_Sh2211, ttll_Var3cDown, ttll_Var3cUp, ttll_H7, ttH_PhH7EG, VH, VV, VVV, SingleTop, Vjets_Sherpa221,
I believe some of them use Sherpa221 and will be re-requested. There are many PHYSLITE derivations missing and we will have to request them.
