Create new derivation HDBS5 for H->aa->yytautau analysis

Boping Chen requested to merge (removed):21.2-HDBS-2022-09-05 into 21.2

This is a request to add a new HDBS5 derivation stream in the DerivationFrameworkHDBS, aiming for the H->aa->2y+2tau analysis, where a dedicated low pT boosted ditau object is used, for the boosted topology in the final state. The requested derivation "inherits" from the TAUP5 derivation, where the low pT boosted ditau object is used for the first time.

Here is the Jira ticket for this request: https://its.cern.ch/jira/browse/ATLHDBSDPD-129

Here is the original TAUP5 derivation Jira ticket, where the only difference is that we've added diphoton triggers to the existing high pT photon triggers: https://its.cern.ch/jira/browse/ATLTAU-1389

Here is the glance page for the analysis: https://atlas-glance.cern.ch/atlas/analysis/analyses/details.php?id=7458

We tested the derivation efficiency for DiphotonBoosted (DSID 364397), our dominant background, for mc16e only. The efficiency is about 10%, so the total number of events for mc16e would be about 9e6.

For data, we tested data18 only. The efficiency is about 1.6%.

The size of the DAOD is around 0.094MB per event for data and 0.106MB per event for MC.
