Cleaning up EXOT8 and adding TAR jet inputs

This MR includes three major changes to EXOT8 for the HH->bbVV analysis:

1. The truth record is changed to the TRUTH3 style
2. Instead of using L1 triggers for skimming, the complete set of relevant lowest unprescaled triggers and the jet support triggers are used
3. Anti-kt R=0.2 jets and inner detector tracks are added as inputs for TAR jets. Thinning is applied to both collections based on the proximity of high-pT large-R jets.

The difference in size is as follows:

Sample	Original size	New size	Difference
Data16	12.16 MB	9.45 MB	-22%
Data17	112.35 MB	86.00 MB	-23%
HH->WWbb 0 lep	1.45 GB	1.52 GB	+4%
