Export types for the objects returned from making requests

[intercepted16]

The export of types of the objects returned when making requests would be incredibly useful. This would significantly enhance the developer experience by:

• preventing incorrect key accesses
• and other invalid operations on the type of an object or value inside the object
• enhancing IDE intellisense
• integration with linters and static type checkers

I guess you could implement this manually, though it would be amazing if the Slack API did this for you.
