Create a new one-shot channel for sending single values across asynchronous
tasks.

The function returns separate "send" and "receive" handles. The `Sender`
handle is used by the producer to send the value. The `Receiver` handle is
used by the consumer to receive the value.

Each handle can be used on separate tasks.
