Add Serialization Messaging (NGWPC-9482)

[idtodd]

This PR adds messaging for creating, retrieving, and freeing serialization states for the T-Route BMI. The extent of the data saved includes data stored on the AbstractNetwork and DataAssimilation objects.

Note: Because of some structural changes to the BMI, this PR must be merged alongside the implementation of state saving in NGEN. Merging prior to the changes made there will break the communication of data between the two.

Additions

• Messaging variables for working with state data.
• Variables on the BMI representing the output results from a T-Route run.

Removals

Changes

Testing

1. Test script demonstrating the new architecture can work with data loaded from NGEN output nexus CSVs.
2. Testing on AWS Workspaces using the state saving branch of NGEN, the output results with the new architecture for sending data from NGEN to T-Route and interpreting that data.
