Cache API requests

[ToastedDev]

This is so we don't have to keep calling the API every time.

An example of an API call that needs to be cached is this one:

countify/bot/src/features/counting.ts

Lines 17 to 19 in f05b089

	const channels = await api.channels.getChannels.query({
	guildId: message.guild.id,
	});
