📄 Description

Updated the SerializationProtocol interface to allow dumpsTyped and loadsTyped to be run synchronously or asynchronously.
Applied await to calls of each function throughout the existing checkpoint savers and tests.

This should allow future users to provide asynchronous serialization and deserialization for their savers, without breaking any current implementations.
