Bumps the external ouroboros-network source-repository-package to the updated peras-staging/pr-5202, which incorporates the changes from: IntersectMBO/ouroboros-network#5202 In addition, it tweak call sites of `nodeToNodeProtocols` to match its updated signature, passing down the enabled feature flags.

Description
Add
NodeToNodeV_16for Peras, and depend onCardano.Base.FeatureFlagWe add a new (experimental)
NodeToNodeVersionfor Peras.Additionally, we add a function
which additionally checks that the
PerasFlagis set, cf IntersectMBO/cardano-base#547. Eventually, once Peras is non-experimental, thePerasFlagwill be removed again.nodeToNodeProtocolsnow depends onSet CardanoFeatureFlag.Add generic ObjectDiffusion mini-protocol
This protocol is going to be used for Peras vote and certificate diffusion. It is essentially a copy of TxSubmission, except that
MsgInitandMsgDoneare sent by the client/inbound side, as the flow of information is the reverse of that of TxSubmission.We also add codec roundtrip tests, but no CDDL just yet, given that we might make further changes to this protocol:
MsgInit: currently pointless, but will get a payload indicating that we are only interested in objects after some indicator.The representation of object ids currently always is a list of object ids. We are potentially going to make this customizable to optimize for cases where a more succinct representation is possible (such as requesting "ranges" of ids).
We might make some changes to how IDs are requested, such as allowing the server to reply with
MsgAwaitReplywhen we do a blocking request, cf Make idleness explicit in ObjectDiffusion mini-protocol tweag/cardano-peras#144.Register Peras vote and certificate diffusion mini-protocols
In
Cardano.Network.NodeToNode, make the Network layer aware of Peras certificate and vote diffusion, gated behind bothNodeToNodeV_16and the experimental Peras feature flag.Checklist
