Reproducible example

use std::io::Cursor;

use polars::prelude::*;

const BASIC_JSON: &str = r#"
{"user": {"name": "test1"}, "id": 1}
{"user": {"name": "test2"}, "id": 2}
"#;

fn main() {
    let file = Cursor::new(BASIC_JSON);

    let df = dbg!(JsonReader::new(file)
        .with_json_format(JsonFormat::JsonLines)
        .finish()
        .unwrap());
    // shape: (2, 2)

Issue description

The function Series::from_any_values_and_dtype assumes all DataType::Struct type holds AnyValue::StructOwned, and dismisses the AnyValue::Struct type and it returns null.

polars/crates/polars-core/src/series/any_value.rs

Line 162 in 25f84e4

DataType::Struct(fields) => any_values_to_struct(values, fields, strict)?,

polars/crates/polars-core/src/series/any_value.rs

Line 693 in 25f84e4

AnyValue::StructOwned(payload) => {

polars/crates/polars-core/src/series/any_value.rs

Lines 726 to 729 in 25f84e4

	_ => {
	has_outer_validity = true;
	field_avs.push(AnyValue::Null)
	},

Expected behavior

not returning null and handling the AnyValue::Struct type
