feat: allow removing properties from cached objects

[TempVoice]

Please describe the changes this PR makes and why it should be merged:
Cache only the properties you need and remove the undesired one. This greatly improves the memory footprint.

For example, the channel.topic property of channels which consumes dozens of bytes. If a bot operates in thousands of servers this can waste unnecessary memory.

const client = new Client({
	undesiredProperties: {
		ChannelManager: ["topic"]
	}
})

Goal is to support caching from other managers too.
I am open for what you guys think about it. I am willing to battle test this for a bot with >150k servers.
