[FEAT] Support for Namespaces

[sasial-dev]

Describe your feature

In a large complex game, the remotes used can generally be grouped into categories. Zap should support a namespace under the event struct, and when a namespace is specified, you should be able to access it through remotes.namespace.remote_name.

Alternatives

• Do not organise the events
• Use mutiple zap config files

Implementation Details

This should be implimented under the event struct with an optional namespace field.

[jackdotink]

An alternative syntax for this rather an an event namespace field could be this:

namespace n = {
	type t = u8
	event e = {
		from: Server,
		type: Reliable,
		call: SingleAsync,
		data: t
	}
}

-- this also allows us to use types from namespaces
type t_from_n = n.t

[sasial-dev]

I do like that alternative syntax better!
