> Similar to pyarrow's export_to_c and import_from_c methods. We have c++
> wrappers like ImportRecordBatch but they aren't exported from the package
> namespace, so attaching them to the R6 objects would provide a way to do
> that.
> Lifecycle management of the C pointers they read/write to (allocate/delete)
> is left outside of these methods (as it is in the non-exported wrappers
> today).
> export_to_c should be a method on an object. import_from_c should be a "class
> method" like {{$create()}}.
> Once this is done, we should inform duckdb of this so that they can remove
> their {{getFromNamespace()}} workaround.
