Create Task API -> 0.7.0

[dfed]

Addresses #50

This PR represents a breaking change of the API. In this PR, we:

• Replaced the .enqueue (and similar) API on both FIFOQueue and ActorQueue with a Task-based API. Now operations can be enqueued on these queues with Task(on: queue). By creating a Task, we now allow consumers to cancel pending tasks.
• Removed the MainActorQueue entirely, and replaced it with Task(on: MainActor.queue)

The good news is that migration is quite straightforward.

• Replace queue.enqueue { … } with Task(on: queue) { … }
• Replace await queue.enqueueAndWait { … } with await Task(on: queue) { … }.value
• Replace try await queue.enqueueAndWait { … } with try await Task(on: queue) { … }.value
• Replace try await queue.enqueueAndWait { … } with await Task(on: queue) { … }.value
• Replace queue.enqueue(on: someActor) { someActor in … } with Task(on: queue, isolatedTo: someActor) { someActor in … }
• Replace MainActorQueue.shared.enqueue { … } with Task(on: MainActor.queue) { … }

These changes enable consumers to store and cancel enqueued tasks.

• The migration instructions specify using the 'isolatedTo' parameter when enqueuing tasks on an actor; consider changing this to 'await Task(on: queue, isolatedTo: myself) { myself in' to fully adhere to the new API.

await Task(on: queue) { myself in
