Is it possible to have multiple instance of "pb" configuration?

I know we have pb.state. But at one time, there can be only one state in effect.

This could be inconvenient if we have multiple applications of protobuf in a project, especially if we are using coroutine.

If this is acceptable, I'd like to create a PR for it.

Maybe you could only add encode/decode/load to State objects. But we need think twice to decide whether to merge it.
