Appending a NULL in UUID[] column panics

[disq]

I thought with #193 for nulls we'd have to use untyped nils for NULL values, doing so doesn't seem to work for uuid[] columns.

panic: interface conversion: interface {} is nil, not duckdb.UUID

goroutine 23 [running]:
github.com/marcboeker/go-duckdb.(*vector).init.(*vector).initUUID.func15(0x1400163a410?, 0x0?, {0x0?, 0x0?})

I tried a typed nil (of *duckdb.UUID) which gave me:
database/sql/driver: could not append row: cast error: cannot cast *duckdb.UUID to duckdb.UUID: column index: 47

So, what's the correct way to insert nulls using appender?

Hi @disq. Could you add a self-contained Go program to reproduce this, please? Then I can have a look

This seems fixed, I no longer get panic: interface conversion: interface {} is nil, not duckdb.UUID
