proxyMap/proxySet performance

[farwayer]

Hello. valtio looks interesting, thanks!

I am now figuring out how the library is suitable for serious development. And I was unpleasantly surprised when I saw the proxySet/proxyMap implementations.

An array is used as a data structure, and .find (and similar) is used to implement methods. Performance on large amounts of data will be terrible. And this is exactly where Map is usually used for speed/memory optimization.

I would advise changing the implementation or, if it is not possible to achieve performance comparable to Set / Map, it is better to remove these methods. Do not mislead library users who expect good performance.

See also #485.

Providing Set / Map impls for performance is out of the scope of this library.
Please consider developing a third-party library for that.
Please feel free to open a PR to fix docs to avoid misleading.

Ah sorry missed #485 discussion. Thanks.
