git submodules have the wrong version

Usecase:
- parent-project with jgitver activated
- module1 is added as a git submodule: `git submodule add path/to/module1.git`

=> parent-project and module1 are in two distinct git repositories, and have their own tags

if parent-project is tagged v1.0.0
and module1 is tagged v2.0.0
then I expect jgitver to release module1 in v2.0.0

but module1 takes the tag from the parent-project and is tagged v1.0.0 :-(

is there a way that jgitver takes the tag of the module1 repo ?
