In this one you did not make the function private. Is that on purpose? Why?

we need it to be public for trie.Database.Node method that was removed in upstream, but we use it in RecordingKV.Get.
Either way, good catch, as I should:
- either add new method
hashdb.Database.Nodefor exposinghashdb.Database.node - or probably better: I should refactor
RecordingKVto not usetriedb.Database.Nodeand usetriedb.Readerthere instead
Taking into account that pathdb doesn't support Node method, seems best to go ahead with second option and use triedb.Reader, so we will be one more step closer to supporting pathdb and also minimizing the diff. What do you think?

I'm really curious if / how well we can implement RecordingKV based off pathdb. I don't know the details.
I assume it's not trivial, so I'd say for this PR let's have a Node function exporting node, and leave pathdb support for a separate PR.

makes sense, I've added the Node method, thanks!
