Draft: Resolve "[scripts] Make prepare_instrumentation.sh indepdent of current directory"
Reason why this change is needed
- It drives me crazy that we first need to either clone or copy the scripts-directory from ivas-codec to ivas-basop...
Description of the change
- detect the root of the source directory using
git rev-parse. If we are not within a git repo, then stick to old behavior - fixes for relative paths in the scripts
Affected operating points
- n/a
