ColTuple issue when using proto.Named() helper

### Describe the bug

### Steps to reproduce
(code taken from slightly adjusted tuple_test.go):
```
require.NoError(t, conn.Do(ctx, Query{
Body: "CREATE TABLE named_tuples (`1` Tuple(`s` String, `i` Int64, `m` Map(String, Float32))) ENGINE = Memory",
}))

// ...

var (
// ...
mapData = proto.Named[map[string]float32](
proto.NewMap[string, float32](new(proto.ColStr), new(proto.ColFloat32)),
"m",
)
)
results := proto.Results{
{Name: "1", Data: proto.ColTuple{strData, intData, mapData}},
}
require.NoError(t, conn.Do(ctx, Query{
Body: "SELECT * FROM named_tuples",
Result: results,
}))
```

### Error log

```

The issue happens only when using `proto.Named` helper because it returns reference to new ColName obj instead of obj itself. This causes `Infer` function does not work properly for this case:
it passes `(Tuple(String, Int64, Map(String, Float32)))` into each of column.Infer call instead of parsing each column separately.

To fix the issue I had to replace
```
mapData = proto.ColNamed[map[string]float32]{
ColumnOf: proto.NewMap[string, float32](new(proto.ColStr), new(proto.ColFloat32)),
Name: "m",
}
```
with
```
mapData = proto.Named[map[string]float32](
proto.NewMap[string, float32](new(proto.ColStr), new(proto.ColFloat32)),
"m",
)
```

In general, this is just usability issue: I've spent a few hours trying to debug why my code don't work - only because I've used (seemingly harmless) helper function `proto.Named`. I think interfaces should be adjusted to ensure the result of `proto.Named()` can't be used as element of `ColTuple` list. At least some clarification needed about what elements should be passed to ColTuple.
