[WIP] Serialization of StagingPaths

[dwhswenson]

This is a subset of the work in #234, split off to facilitate review. This PR will merge into #258 (making it easier to see the additions specific to the PR, but meaning that this should be merged before that)

This handles the serialization of StagingPath objects. (detailed description will be coming in a future edit)

TODO:

• [x] Add user story where the type of external storage is changed
• [x] Add user story where the a new JSONCodec is added after the StagingSerialization is created.
• [x] Docstrings
• [x] Attach to the StorageManager
