Summary
RocketPyEncoder/RocketPyDecoderto round-tripnumpy.random.SeedSequencevia its reconstructible state (entropy,spawn_key,n_children_spawned,pool_size) plus a class signature.TypeError: Object of type SeedSequence is not JSON serializablewhen dumping sensors (or any object) that hold aSeedSequenceseed, including spawned child sequences used for parallel Monte Carlo.Fixes #1087
Test plan
