Dataset does not serialise

[IsakNaslundBh]

Broken rules:

https://github.com/BHoM/EmbodiedSuffering_Toolkit/blob/develop/DataSets/EmbodiedSuffering/Slavery/GlobalSlaveryIndex.json

Does not deserialise. It is still targeting the "Slavery" class that was changed in https://github.com/BHoM/EmbodiedSuffering_Toolkit/pull/18/files

Suggestions to restore compliance:

Remove or re-serialise dataset using current oM types.
