Bump asgiref from 3.2.3 to 3.4.1 in /server

[dependabot-preview]

Bumps asgiref from 3.2.3 to 3.4.1.

Changelog

Sourced from asgiref's changelog.

3.4.1 (2021-07-01)

• Fixed an issue with the deadlock detection where it had false positives during exception handling.

3.4.0 (2021-06-27)

• Calling sync_to_async directly from inside itself (which causes a deadlock when in the default, thread-sensitive mode) now has deadlock detection.

• asyncio usage has been updated to use the new versions of get_event_loop, ensure_future, wait and gather, avoiding deprecation warnings in Python 3.10. Python 3.6 installs continue to use the old versions; this is only for 3.7+

• sync_to_async and async_to_sync now have improved type hints that pass through the underlying function type correctly.

• All Websocket* types are now spelled WebSocket, to match our specs and the official spelling. The old names will work until release 3.5.0, but will raise deprecation warnings.

• The typing for WebSocketScope and HTTPScope's extensions key has been fixed.

3.3.4 (2021-04-06)

• The async_to_sync type error is now a warning due the high false negative rate when trying to detect coroutine-returning callables in Python.

3.3.3 (2021-04-06)

• The sync conversion functions now correctly detect functools.partial and other wrappers around async functions on earlier Python releases.

3.3.2 (2021-04-05)

• SyncToAsync now takes an optional "executor" argument if you want to supply your own executor rather than using the built-in one.

• async_to_sync and sync_to_async now check their arguments are functions of the correct type.
