Export types for the objects returned from making requests

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.

Requirements

Please read the Contributing guidelines and Code of Conduct before creating this issue or pull request. By submitting, you are agreeing to those rules.

Inizia da slack_sdk.web.WebClient, l'unica area client selezionata nell'issue, e leggi le linee guida per i contributi collegate prima di analizzare come sono rappresentate le risposte della Web API. Definisci l'ambito dei tipi di risposta esportati e il modo in cui coprirebbero le richieste sincrone e asincrone; il completamento dovrebbe fornire tipi utilizzabili che supportino il controllo delle chiavi, il completamento nell'IDE, i linter e i type checker statici.
