Map modules to TS namespaces

[tijmenb]

Currently a serializer inside a module will be output as a single type, eg Nested::AlbumSerializer becomes a NestedAlbum:

types_from_serializers/spec/types_from_serializers/__snapshots__/interfaces_Nested__AlbumSerializer.snap

Lines 7 to 11 in b47ac0f

	export default interface NestedAlbum {
	id: AnyModel['id']
	title: AnyModel['title']
	tracks: Song[]
	}

There's some support for putting types into namespaces: #9

Idea

Wondering if it make sense to add a module_into_namespaces option, that will instead use the module name(s) to generate the namespace:

export namespace Nested {
  interface Album {
    id: AnyModel['id']
    title: AnyModel['title']
    tracks: Song[]
  }
}

This makes it easier to import all types for a single module, and keeps the Ruby and TS more in sync.

Unanswered questions:

• Any unforseen problems with this?
• Can this be implemented without too much overhead?
• Would all namespaces types live in a single file?
