Some convenient utilities for asyncio.

Utilities include:

- [`@async_main`](src/asyncio_addon/decorator.py): A decorator to run an async function as the main entry point.
- [`run_sync`](src/asyncio_addon/sync.py): Run a coroutine in sync, even if the async event loop is running.
- [`run_async`](src/asyncio_addon/sync.py): An alias of `asyncio.to_thread`. Run a sync function in a separate thread.
- [`SemGroup`](src/asyncio_addon/task_group.py): A task group with a semaphore, allowing limited concurrency.
- [`gather_all`](src/asyncio_addon/task.py): Enhanced version of `asyncio.gather` with concurrency control, better API and cancel-safety.

(Almost) everything natively include `timeout` control.

## Why do we need another `gather_all`?

As the [doc](https://docs.python.org/3/library/asyncio-task.html#asyncio.gather) says:

> A new alternative to create and run tasks concurrently and wait for their completion is asyncio.TaskGroup. TaskGroup provides stronger safety guarantees than gather for scheduling a nesting of subtasks: if a task (or a subtask, a task scheduled by a task) raises an exception, TaskGroup will, while gather will not, cancel the remaining scheduled tasks.
