Helper for waiting on asynchronous conditions to be met.

ExWaiter

Handy functions for rate limiting, polling, and receiving.

• Rate Limiting: limit_rate/2 enforces a configurable token bucket rate limit.
• Polling: poll/1, poll!/1, and poll_once/1 periodically check that a given condition has been met.
• Receiving: receive_next/2 and receive_next!/2 return the next message/s from the mailbox within a timeout.
