[L1T] Adding a reduced data format: phase2_l1scout for use in the Spring24 MC Campaign (Phase 2)

[eyigitba]

PR description:

Adding in new configuration options providing a reduced data format: phase2_l1scout for use in the Spring24 MC Campaign. Previously disucssed a bit in #51259 and in #51319

I modified @BenjaminRS's PR based on @mmusich suggestion.

The idea behind this is to reduce the event size by a factor of ~50 to be able to request more MC statistics for Phase-2 L1 Scouting use.

PR validation:

Ran the code locally over ~50 events using Phase2Spring24 MC campaign setup commands. It produces the expected result without crashing. File size goes from ~3 GB to ~100 MB.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

Related to #51319

Please let me know which other releases should get a backport of this PR
