add sharded-queue library

[nekufa]

What is this Python project?

Imagine your job queue operates at very high rps and needs distribution over multiple workers. But you need to keep context-sensitive requests in same thread and manage thread request processing priority. In other words, sharded queue is a queue with sub-queues inside. Tasks are executed in FIFO order and you define how to route them correctly per handler basis.

What's the difference between this Python project and similar ones?

There are no libraries that can be used for sharding and prioritize job queues keeping strict order
