Optimize Embeds away if the non-embeds are already queried

Embeds seem to be useful as they reduce the amount of API calls needed, but at the same time, they can cause issues with the current Caching implementation, as the elements might already be queried, but the embedded API call has not been done yet. So it causes more queries instead of less queries.

Simply stripping the ?embeds=... from the URL when comparing, doesn't work, because the embedded objects might not be queried yet. If there's more than 1 embedded object that it wants to access, it would cause more queries then. So this isn't really a good solution.

首先跟踪当前的 Caching 实现，以及如何比较带有 ?embeds=... 的请求 URL。定义对于已查询的非嵌入对象和多个嵌入对象的行为，然后验证在不跳过必需嵌入数据的情况下避免冗余 API 调用。
