Thanks, the main code looks good!
Unfortunately, this seems to wither break the compatibility with prior
savepoints (when Avro types were implicitly handled through Kryo, now bridged
through the `BackwarsCompatibleAvroSerializer`) or needs to adjust that test.
There are also some license header issues, causing the build to fail.---
