Could you describe how you'd want to use this please?

Mainly add custom codec registries lmao, but surely there's more stuff that people would need if they want to mess with the settings

Sure, let's add a method to easily add Codec registries and then also just give them the MongoClientSettings object instance so they can do what they want
