Description

It should be possible to implement ByteBufferSerializer as well, using Jackson's ByteBufferBackedOutputStream/ByteBufferBackedInputStream

This might be more performant for serialization in Artery.

Research direction
The issue requests implementing a ByteBufferSerializer for Jackson using Jackson's ByteBufferBackedOutputStream/ByteBufferBackedInputStream. To start, examine existing serializer implementations in the Akka codebase, particularly in the akka serialization jackson module. Look for how other serializers are defined and registered. The new serializer should be similar but optimized for ByteBuffer usage. Check if there are any comments or linked PRs for guidance; none are visible in this issue. Implement the serializer, write tests, and submit a PR.
