Proper way of typing results

Hi,

From the documentation and especially the "Inspect Data Values" section, it's not clear for me how to get proper value typings based on column types.
From what I understand `columnType` and `columnValue` are coming from different function return (probably from `getColumnTypes()` and `value()` for instance).

I don't think there's a trivial way to get the data type inferred like that, so in your example do you suggest to cast the corresponding column value based on its column type ?

Example :
```typescript
if (columnTypes[0].typeId === DuckDBTypeId.VARCHAR) {
const value = result.value(0, 1) as DuckDBArrayValue; //fetching same column, row: 1
value.items // ok
}
```

Is there a better way using your api ?
