Typings: Export named types used in structures returned from the api

[antipoly]

The typings in this package currently aren't exported to be used externally, which means that extracting types from Api methods would work something like:

ReturnType<OpenBlox['Classic{API}']['{Method}']>['data']

In each Api folder, the .types.ts file contains all the named types, but they aren't exported in the index.ts file.
This can easily be fixed by exporting the types in the index.ts file of each Api module folder.

export * from "./~.types";
