Backcompatability of objects produced by EnsembleKalmanProcesses.jl

[odunbar]

If one uses a CES pipeline to create CaibrateEmulateSample.EnsembleKalmanProcessModule.EnsembleKalmanProcess types, then they can be saveable e.g with JLD2 and loadable, given that one has a using Calibrate....Process statement in their code.

However it does not allow the loading of the (exact same) module EnsembleKalmanProcesses.EnsembleKalmanProcess (these are the same, as they are simply imported from the package).

Is there a way to get this back-compatability (easily), so users who originally using EnsembleKalmanProcesses can load them into CES
