fix: GeneratedParticles: ignore MCParticles with generatorStatus != 1 (…

…#772)

### Briefly, what does this PR introduce?
The GeneratedParticles branch all MCParticles which are thrown into the
detector, in the ReconstructedParticles format (for easy comparison).
This means we should not include generatorStatus == 0 as was the case
until now.

### What kind of change does this PR introduce?
- [x] Bug fix (issue: GeneratedParticles includes more particles than
intended)
- [ ] New feature (issue #__)
- [ ] Documentation update
- [ ] Other: __

### Please check if this PR fulfills the following:
- [ ] Tests for the changes have been added
- [ ] Documentation has been added / updated
- [ ] Changes have been communicated to collaborators

### Does this PR introduce breaking changes? What changes might users
need to make to their code?
No.

### Does this PR change default behavior?
Yes, excludes secondary particles (which should be determined from
MCParticles based on the bit pattern in simulatorStatus).
