[CI] Object editing sanity test

Tests for object editing are being added to selftest.prm here: !1933 (merged). This will check BE for this feature in every MR.

For e.g. JBM, we have a sanity check test which checks bitexactness between no JBM and JBM with a neutral delay profile (which should not trigger any modification of the output signal by the JBM). Does this also make sense for Object-editing?

Idea:

• Create outputs without object editing
• Run same decoder operating points again, this time with object editing, but feeding the output metadata files from first run
• Check for bitexactness

From my (limited) understanding of the object-editing feature, this should result in bitexact output if everything works as expected, but I would need experts to comment on that.
