Subject: [PATCH] feat(CompareCommand): Add the `SEMANTIC_DIFF` as a new
 compare method

The new compare method `SEMANTIC_DIFF` can be used for comparing the
ORT results on the object level. Currently, it only checks whether
the provided ORT results are equal. There will a improved comparison
of the results in the upcoming commit(s).
