evdev/eventio_async.py: python3.11 compatibility

[AndrewAmmerlaan]

From the Python 3.11 Changelog:

The @asyncio.coroutine decorator enabling legacy generator-based coroutines to be compatible with async/await code. The function has been deprecated since Python 3.8 and the removal was initially scheduled for Python 3.10. Use async def instead. (Contributed by Illia Volochii in bpo-43216.)

This small change should make things work with python 3.11, the tests are passing for me.

I'll look into this soon, thanks

This doesn't work anymore with your change in Python 3.10.4:

import evdev
import asyncio

async def main():
    keyboard = evdev.InputDevice("/dev/input/event7")
    async for event in keyboard.async_read_loop():
        print(event.type, event.code, event.value)

loop = asyncio.new_event_loop()
loop.run_until_complete(main())

python-evdev tests are very rudimentary afaik. I found this by running input-remappers tests

according to the python docs __anext__ should return a Awaitable which this function already does. So there is no need to use the async keyword. async def would wrap the whole function again inside a awaitable making it necessary to await this function twice.

Suggested change

	async def __anext__(self):
	def __anext__(self):

As for the @asyncio.coroutine: I think this was never needed as it was meant for generator-based coroutines which this function is not.

I did some quick tests with python3.8 and 3.10. This seems to work fine.

Hi. I think this is the correct solution indeed. Will release a new version asap. Thanks!
