Feature Request: Print Different Levels of HNSW Graph

[AdeelAslamUnimore]

I would like to request a feature that allows for printing the different levels of an HNSW graph in HNSWlib. This would help users better understand the structure of the graph and visually inspect the organization of nodes across different layers.
Both for C++ and python
