Properly fixed the busted migration issue
Updated to the latest version of Quick and Nimble (unit testing libraries)
Updated the tests based on the above
Started writing up wrappers and unit tests for group config types
Refactored some duplicate batch & prepared request code to be more generic and reusable
Renamed a number of legacy closed group functions to have the term 'legacy' in them for ease of coding
Added parallelisation for the unit tests

Fixed a broken unit test
Fixed a possible divide by zero error
Cleaned up some of the id blinding methods (ie. removing handling for impossible error states)
Added unit tests for the new Sodium methods (used for id blinding)
Added unit tests for some of the shared code
Added unit tests for the MessageSender+Encryption extension functions

Updated the unit test key constants to be consistent with the SOGS auth-example keys for consistency
