Geant4DetectorConstruction: forward debugLimts, printPlacements, printSensitives to Converter code from plugin

Used for Geometry debug flags

 - units from properties specified in ddsim_steer.py
   already are in G4units, so no conversion needed

DDSim,Meta: Fix formatting for dict

The ddsim --meta.runNumberOffset command-line argument doesn't work
correctly (and similarly for event number).

On a machine running

```
LSB Version:    :core-4.1-amd64:core-4.1-ia32:core-4.1-noarch
Distributor ID: Scientific
Description:    Scientific Linux release 7.3 (Nitrogen)
Release:        7.3
Codename:       Nitrogen
```

I do

```
. /cvmfs/sw.hsf.org/key4hep/setup.sh
```

The then command

```
ddsim  --compactFile $LCGEO/FCCee/compact/FCCee_o1_v05/FCCee_o1_v05.xml -G -N10 --outputFile out.edm4hep.root --meta.runNumberOffset 735001  2>&1|tee log
```

eventually crashes with the error

```

The arguments are never converted from strings to integers.
The change here fixes this.

Allow users to add track user information to G4 tracks, which then moves to Geant4Particle for saving

This adds the arguments `--gun.etaMin` and `--gun.etaMax`. If both
`thetaMin` and `etaMax` are specified, `etaMax has precedence.

If excited state is already known we get it via FindIon. Otherwise we use GetIon to create zero-state ions and print warnings for lvl>0
