* Move waku.nim from waku/factory to under waku/
* remove unused
* Realize Kernel API in scope of Waku class
* Refactor waku/api into messaging_client, waku/api/types and api_conf into logos_delivery/api
* Make liblogosdelivery and wakunode2 compile, remove waku/api.nim as it was just a import orchestrator
* make test compile and run
* Reconcile master's new send tests to LogosDelivery API after rebase
master commits #3965/#3669-followup added two test cases (Edge lightpush
delivery #3847, store-validation timeout) written against the removed
waku/api.nim createNode helper. Rewrite them to the LogosDelivery shape:
createNode -> LogosDelivery.new, node.node -> node.waku.node,
node.brokerCtx -> node.waku.brokerCtx, node.send -> node.messagingClient.send,
and drop the now-implicit mountMessagingClient calls (LogosDelivery.new
mounts the client internally).
* make validateRoots async
* add on-demand refreshRoots functionality
* Move max rootsrefresh time to constants
* make generateProof async and add ensureFreshMerkleProofPath
* Update to match code format and linting
* Use Wakumessage.new()
* Add trigger for client side only merkleproofcache updates
* full decoupling of updateRoots and merkleproofcache update
* Fix isNil check format
* Move moment check to top of roots and merkle path update procs
* Update PathCheckMinInterval
* Add tests for on demand merkle path updates
* Replace appendRLNProof and use message.toRLNSignal
* Fix linting
* Remove commented code
* Remove more old commented code
* Fix formatting and simplifications
