Composite hash types

Within the system a hash system is used to help detect changes between successive data extractions and match records. This includes the creation of 'composite hashes' for groups of related records, which have an integer code that indicates the record type. These codes are listed below.
Note that neither the hashes nor the codes feature in the final core MDR database and they do not form part of the JSON files generated by the system.
