2024 01 02 encapsulate state p2psink (#5342)

* Move NodeState back to node module

* Refactor peerWithServicesDataMap into NodeState

* More usage of state.peerDataMap in stream

* Fix log message

* Fix compile

* Move PeerFinder into NodeState

* WIP: Move PeerFinder init into NeutrinoNode.start()

* Get things mostly working again after rebase

* Fix bug in handling of headers message where we wouldn't transition to DoneSyncing if a peer sent us 0 headers

* Move SendToPeer into stream

* scalafmt

* Empty commit to run CI

* Re-add DataMessageHandlerTest

* Renable disconnecting portion of NeutrinoNodeTest

* Empty commit to run CI

* Remove disconnection part of test again

* Empty commit to re-run CI

* Empty commit to re-run CI
