ClickHouse table function is recognized as TableFactor::Table

See https://clickhouse.com/docs/sql-reference/table-functions.

For example:
```sql
SELECT * FROM test;
SELECT * FROM test();
```

They produce:

> pre_visit_table_factor: Table { name: ObjectName([Identifier(Ident { value: "test", quote_style: None, span: Span(Location(1,16)..Location(1,20)) })]), alias: None, args: None, with_hints: [], version: None, with_ordinality: false, partitions: [], json_path: None, sample: None, index_hints: [] }

and

> pre_visit_table_factor: Table { name: ObjectName([Identifier(Ident { value: "test", quote_style: None, span: Span(Location(1,16)..Location(1,20)) })]), alias: None, args: Some(TableFunctionArgs { args: [], settings: None }), with_hints: [], version: None, with_ordinality: false, partitions: [], json_path: None, sample: None, index_hints: [] }

The second version produces `args: Some(TableFunctionArgs { args: [], settings: None })`.

As I see it's because [`Function`](https://github.com/apache/datafusion-sqlparser-rs/blob/b8539a52af7419b86d9c2fc51ba247d022f7a6f8/src/parser/mod.rs#L13498) is only recognized after a `LATERAL` keyword, and [`TableFunction`](https://github.com/apache/datafusion-sqlparser-rs/blob/b8539a52af7419b86d9c2fc51ba247d022f7a6f8/src/parser/mod.rs#L13511) is only for the `TABLE()` syntax (but not for `ident()`).

Comienza en src/parser/mod.rs, en el manejo de Function y TableFunction enlazado en el issue, y compara después el parsing de SELECT * FROM test y SELECT * FROM test(). Confirma el comportamiento completado con una salida del parser que distinga adecuadamente la forma ident() de ClickHouse de una referencia a una tabla simple.
