feat(gservice): consider impl `#[panicking]` macro for fns in service

[breathx]

The macro will require Result in return type, but it only will be for ability to use ?. On expand it will unwrap() the result and return only Ok(T)

[DennisInSky]

@breathx can you please elaborate on this? Any examples of usage?

[DennisInSky]

@breathx better description is on you

fn mint(&nut self, value: u64) -> bool { ler r: Result<bool, String> = some_func(); r.unwrap(); // intentionally }

[panicking]

fn mint(&nut self, value: u64) -> Result<bool, String> { ler r: Result<bool, String> = some_func()?; }

[vobradovich]

Wouldn't it be better to use the existing route attribute with the unwrap_result prameter?

#[route(unwrap_result)]
fn mint(&nut self, value: u64) -> Result<bool, String> {
    ler r: Result<bool, String> = some_func()?;
}
