Move to L1Nano

[artlbv]

We want to move from L1 menu ntuples to the nanoAOD-based menu ntuples "L1Nano":
https://github.com/cms-l1-dpg/Phase2-L1Nano

The nano contains almost all the relevant objects as in the old menu ntuples except:

• A single EG barrel+endcap collection, see Add HW variables for standalone EG objects Phase2-L1Nano#1
• GTT/tracker-only objects: Add GTT/tracker-only objects Phase2-L1Nano#10

In addition to the previous "L1 objects" also "GT objects" were added. a summary of the current content is shown here:
https://alobanov.web.cern.ch/L1T/Phase2/L1Nano/l1nano_doc_report.html

This branch/commit tried a first version of adapting the cache and object performance code to the L1Nano: 9a1aa4a
https://github.com/artlbv/Phase2-L1MenuTools/tree/dev_nano

Note that apart from the (branch) name changes of the L1 objects, the major change for this framework is the update of the generator-level particle collections.

Instead of storing all particles, the default, filtered, GenPart collection is used now:
https://alobanov.web.cern.ch/L1T/Phase2/L1Nano/l1nano_doc_report.html#GenPart

The migration to nano can be split in these tasks:

• Adapt the framework cacheing to nano
• Validate that GenPart and the old genpart_x reference objects are compatible #59
• Compare the distributions of the L1 objects in the old menu vs the new nano ntuples
• Migrate the plot /rate configs to nano
• Validate the plot/rate for old vs nano ntuples
