• add sync method for rbatis
  create table if not exists, add column if not exists

  use rbatis::RBatis;
  use rbatis::table_sync::{SqliteTableMapper};
  
   let rb = RBatis::new();
   let conn = rb.acquire().await;
  pub async fn do_sync_table(rb: &RBatis){
        let map = rbs::to_value!{
              "id":"INT",
              "name":"TEXT",
       };
       let _ = RBatis::sync(&rb,&SqliteTableMapper{},&map,"user").await;
  }

  use rbatis::RBatis;
  use rbatis::table_sync::{SqliteTableMapper};
  
  #[derive(Clone, Debug, serde::Serialize, serde::Deserialize)]
