High level summary​

As part of the tech dept reduction efforts we have restructured how stake is being computed, thus also removing Ptr from stake distribution computation for Conway. Various minor serialization fixes and failure reporting improvements.

We also added missing tests for block serialization roundtripping and CDDL conformance, which led to us removing a bug in Babbage CDDL specification.
