Support more basic types, even customized structs in oai parameter

[RWDai]

Description of the feature

https://docs.rs/poem-openapi/latest/poem_openapi/derive.Object.html
oai parameter default is only support bool,string.
Can we support more basic types, even customized structs？

Code example (if possible)

/// example
#[derive(Object)]
struct example {
    
    id: String,

    #[oai(default=3306)]
    mysql_port: u32,
}

Maybe looks like serde-rs/serde#368 ?
