Enhancement for ZABAPLINT_DEPENDENCIES to allow branches to be used

[ed-holland]

The abaplinter supports branches for the dependency repository.

Only the generator ZABAPLINT_DEPENDENCIES does not.

Request
Extend the report ZABAPLINT_DEPENDENCIES to allow for the input and use of a branch to create the dependent objects.

Note: we are working on implementing it.
