Convenience module that re-exports the PubSub API.

This module delegates all functions to Dala.Platform.Pubsub, providing a shorter and more ergonomic API:

# Instead of:
Dala.Platform.Pubsub.subscribe(pubsub, "topic")

# You can write:
Dala.PubSub.subscribe(pubsub, "topic")

See Dala.Platform.Pubsub for full documentation.
