MID Innovator: B.1.0 import+export test + updated A.1.0 roundtrip

Hello,

I'd like to introduce the following changes to the repository:

- Rerun the roundtrip test for test case A
- Run the import and export tests for B.1.0
- Adjust the wording in results.xslx in order to make it more consistent

Best Regards,

Matthias
