/** ## `retry` : 允许Pormise失败进行重试
会执行重试的情况:
1. `Promise`返回{@link Err}类型的数据
2. `Promise`的状态是`rejected`

如果重试超过重试次数,会返回{@link RetryError}
@param promiser - 返回一个`Promise`的纯函数
@throws 当`max_wait<min_wait`时异常: {@link IllegalOperatError}
@example
```ts
  let count = 1

  const pm = async () => {
    if (count < 5) {
      count++
      if (count % 2 === 0) return UnexpectedError.err()
      else throw UnexpectedError.new()
    } else return Ok()
  }

  const res = await retry(pm, 5, { max_wait: 1000 })

  assert(res.is_ok)
