Usage

fn main() {
    let header = BoundedVec::from_array("eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9".as_bytes());
    let payload = BoundedVec::from_array(
        "eyJpc3MiOiJPbmxpbmUgSldUIEJ1aWxkZXIiLCJpYXQiOjE3MjkyOTkxODYsImV4cCI6MTc2MDgzNTI1NywiYXVkIjoid3d3LmV4YW1wbGUuY29tIiwic3ViIjoianJvY2tldEBleGFtcGxlLmNvbSIsImZpcnN0X25hbWUiOiJKb2huIiwibGFzdF9uYW1lIjoiRG9lIiwiZW1haWwiOiJqb2huQGRvZS5jb20ifQ"
            .as_bytes(),
    );
    let signature =
        BoundedVec::from_array("Km5zQjxqq7tkHLNdGy-Rq3f05j3IqBUUNxeyvRPXXMI".as_bytes());

    let jwt = JWT::new(header, payload, signature);
    let secret_key = BoundedVec::from_array("secret_key".as_bytes());
    let res: bool = verify_jwt(jwt, secret_key);
}
