Add truth3 content ftag5
FTAG5 was missing "TRUTH3" content, so this MR adds it. This might also be useful to @miochoa.
There are also some changes that @zmarshal and @jcatmore might be interested in:
- I'm adding a few collections to
CollectionsOnTheFly.py
to avoid some boilerplate in derivations - I'm adding a function to
DerivationFrameworkMCTruth.MCTruthCommon
calledaddTruth3ContentToSlimmerTool
which adds the full TRUTH3 content
