for VHmet take photons in barrel and endcap
Modifs to signal model escale and smearing systematics:
- changed treatment of global energy scale
- remove nuisances from formulas if they don't produce an effect
Fixed typo in energy scale formula in parametric model
Merge branch 'topic_signal_model_patches' of github.com:musella/h2gglobe into signal_model_patches
Fix for photonIdMva systematics which was not working with the `doDiPhoMvaUpFront` flag.

- Added dedicated single photon smearer.
- Added array to cache photon id mva in LoopAll.
- This also properly accounts for changes in preselection efficiency.
- Cached values are already shifted by systematic uncertainty.
- FIXME: if doDiPhoMvaUpFront is not active, the old method is used.
- FIXME: need to move photon ID corrections inside the smeaer (ok for now since there are none).
- Also removed unused MvaAnalysis class and hard-coded photonIdMva systematics
A few patches for systematic propogation in signal model.
Typo fix. Prevent printing nan in card
Make recursive fractions by default
Change foolish default settings
