General Issue: Replace XXBLFL with XXLOBXFL

[bundfussr]

Background Information

In the SDTMIG 3.3 the new variables XXLOBXFL were introduce, which should replace the XXBLFL variables.

The test data should be updated accordingly. The domains eg, lb, and vs are definitely affected. It should be checked if other domains are affected.

Definition of Done

In all domains the variables XXBLFL are replaced by XXLOBXFL.
