Create the NotFoundError

Overview of the Feature Request

For now any error returned by the API in a read operation returns a ReadError, which includes the message with the HTTP error code as a very simple string, but we can define a new NotFoundError that extends ReadError also including more refined data. This way we can safely identify a not found error within the block catch of the promise, and carry out the necessary actions in the SPA.

首先追踪 js-dataverse 中现有的 ReadError 实现以及读取操作的错误处理。确定 API 未找到响应在哪里被转换为错误，以及那里有哪些经过细化的数据可用。完成的标准是：在 promise catch 中可以识别出一个独立的 NotFoundError，同时保留现有的 ReadError 行为。
