add "aiofiles.path.walk" or "aiofiles.path.listdir"

[David-xian66]

I want to do the folder traversal operation, but aiofiles doesn't seem to support it

I suggest adding this

(Can you help me?)

I'd like to see this too.

@David-xian66 , @jreadey , hello:

• https://docs.python.org/3/library/os.html#os.listdir -> os.listdir -> already implemented ( https://github.com/Tinche/aiofiles/blob/main/src/aiofiles/os.py#L48 )
• https://docs.python.org/3/library/os.html#os.walk -> os.walk -> seems to be missing, therefore added in the PR Add os.walk wrapper #193 (please review if you like)

I don't see any of requested function to have place in the os.path module. Maybe I misunderstood you, so could you help, please?
