Can not use `Run3' as data type for the bool test because not defined in RICH digitisation configuration

The following discussion from !663 (merged) should be addressed:

@gcorti started a discussion: (+2 comments)
```
app.DataType = "Run3"
```
does not work?

Unfortunately it odes not work with the error

RuntimeError: ERROR : RICH digitisation for Run3 (unknown DataType: 'Run3')

Issue can be closed once merged !718 (merged)
