Solve the problem of @asyncio.coroutine

[OmarR5551]

To solve the problem:

1- Update the mega.py library to the latest version.
2- Downgrade the tenacity library to version 5.1.5.
3- Remove the line before the call function.
4- Go to the _asyncio.py file and modify the call function to the following:

async def call(self, fn, *args, **kwargs):   # Use async here
    self.begin(fn)

    retry_state = RetryCallState(
        retry_object=self, fn=fn, args=args, kwargs=kwargs)
    while True:
        do = self.iter(retry_state=retry_state)
        if isinstance(do, DoAttempt):
            try:
                result = await fn(*args, **kwargs)   # Use await here
            except BaseException:
                retry_state.set_exception(sys.exc_info())
            else:
                retry_state.set_result(result)
        elif isinstance(do, DoSleep):
            retry_state.prepare_for_next_attempt()
            await self.sleep(do)   # Use await here
        else:
            return do
