Explain what you would like to see improved and how.

Currently, the RNTupleImporter does not allow creating ntuples inside a directory within the destination file. This makes it less straightforward to preserve the structure of a file containing multiple directories with multiple TTrees during the conversion.

If the specified fNTupleName is "dir/subdir/TupleName", the importer should create the necessary directories and place the RNTuple inside.
