Requires AthAnalysis,24.2.38 (slow start up due to ATLINFR-5215)

Major reorganisation:
- Rearranged some module names for a more consistent naming scheme
- Reorganised CI tests and added capability to run all locally
- Flags are locked centrally after creation, only modified by yaml or CLI
- Moved container name specification into yaml
- Move CP alg configuration to use ConfigBlock/ConfigAccumulator
  - This changes the overlap removal handling in the ntuples to write out a decoration instead of OR-ed containers due to limitations in the output tree alg.

- Convert of flags.Analysis into ConfigItem class that behaves like an immutable dict
- Generalise HH truth decay algorithm to handle multiple decay modes
- Optimise TTree output by selecting branches for systematic variations
- Add linking between nominal and systematic variation objects

Fixes:

- Disable overlap removal branches for MET

Documentation:

Specific diffs can be viewed on !177.

Other notable changes:
- Change TTree branch output name `recojet_antikt4` -> `recojet_antikt4PFlow`

Branch naming conventions enforced
