do we know all of the possible arrow extension types that are considered not extension by Vortex? Is it just Variant? |

It does feel a bit strange that we pass in both the Vector vtable as well as the extension dtype here? Maybe we don't care

Don’t you need to fix this as well to handle non ext dtypes?

Summary
Allows importing/exporting vortex and arrow arrays in the case where the arrow side is an extension but Vortex isn't.
This PR also includes the motivating change - support for ParquetVariant import/export.
API Changes
Changes the signature of
ArrowImportVTable::from_arrow_arrayto include both theField(which has the full arrow-side type info) and a full vortexDType.
