Review Comment:
> Are you trying to make the CDataReferenceManager usable in code that
supports other ReferenceManager implementations?
This would be helpful for a project I'm currently working on. For
`CDataRefereneceManager` specifically, though, do you know if there's
_currently_ any way to copy a `ValueVector`? I'm essentially trying to clone a
VectorSchemaRoot that's read from a Parquet file into a `RootAllocator`.
