Support for Valkey - Valkey backend

[rkrell]

Most big cloud providers offer Valkey as the cheaper and faster alternative to Redis OSS, Valkey is also meant to be open source forever, since Redis is monetized for cloud providers after 7.2 due to their latest commercial ambitions.

Switching to valkey is almost plug-and-play, but the recommended Python client is valkey-py.

cachews is still stuck on Redis only, would it be possible to add a backend for valkey, similar to the redis backend for cashews?
Do you have any statement about the compatibility to Valkey in the current version?

I tested the cashews with Valkey and it all worked.
As I see the main difference between original redis-py lib and valkey-py lib that last one use libvalkey to parse "response" for better performance. So adding a valley backend make sense.
