Add support for node deletion

[alinalex1392]

I need to support the following use-case, I have a yaml-path, and based on that I need to delete the node represented by it. Until now I did not find anything in the library, the filter functionality is not working how I think about it. Do you have anything in the library to support that?

Edit:
Another use case that could help me, would be to add YAML tags by YAML paths, it is something that can be done with the library?
