Added a couple more dependencies for unit testing injection
Updated the MessageSender to set the sender of the message to the appropriate blinded/unblinded key
Updated the OpenGroup Message to handle verification of both blinded and unblinded messages
Updated the MessageSender to use dependency injection for it's sendToOpenGroupDestination method
Updated the JSONDecoder to support getting dependencies (for signature verification)
Fixed tests broken by updating the signing logic
Got the updated blinding logic working (at least when authenticating a request - still need to deal with message signing and verification)
Storing the server capabilities in the database now so we can correctly blind requests based on them
Renamed the remaining 'v2' functions and classes to just be 'OpenGroup' since there isn't a 'V2' anymore
Cleaned up a few TODOs and functions
Added some new properties to the OpenGroupV2
Moved a number of methods and variables from OpenGroupAPI to OpenGroupManager (anything doing actual logic)
Moved the message signing into the OpenGroupAPI (since that's the only place it happens)
Renamed remaining old model classes to start with 'Legacy' to make clean up easier
Updated the OpenGroupAPI poll method to use the same logic as it previously did to determine if it should retrieve recent messages or messages since the last one
Cleaned up the OnionRequestAPI so we don't need the LegacyOnionRequestAPI
Added requests for the user endpoints
Added deprecated flags to the legacy endpoints and functions
Added some logic to start handling the new poll (batch) response
Started adding unit tests for the OpenGroupAPI functions
Added in the v4 onion requests logic
Added in the new pin/unpin APIs
Split up additional legacy methods to try and simplify the refactoring
Added a number of TODOs around usage of legacy request methods
Updated the MessageSendJob to support V4 messages (V2 messages will be upgraded to V4 if they get re-encoded)
Renamed the Message+Destination from 'openGroup' & 'openGroupV2' to 'legacyOpenGroup' and 'openGroup'
Started plugging in more of the V4 APIs
Renamed a number of the V2 APIs to start with 'legacy'
Split the OpenGroupAPIV2 into separate files
Started working on the new auth and blinded-id approaches (new auth working with un-blinded id suggesting blinded-id code is incorrect)
Updated the SOGS request/response types to use Codable
Updated the SOGS Request type to use enums instead of strings for keys (to reduce likelihood of typos breaking things)
Updated SessionMessagingKit to use Codable and JSONEncoder/JSONDecoder instead of the legacy JSONSerialization
Cleaned up some naming conventions in the SessionMessagingKit (calling a URLRequest body 'parameters' is very confusing...)
Removed the custom TSRequest class (just using standard URLRequest everywhere instead)
Added a number of extension functions to enable some more functional-coding styles
Added extensions to Sodium methods to allow scalar multiplication and the ability to hash providing a salt and a personalisation value (both needed for new SOGS auth)
Fixed an issue where the legacy auth for SOGS could crash due to threading issues (multiple threads accessing the same variable)
Fixed an issue where if you were in two rooms in a single SOGS and deleted one of them, the other room would stop getting updates as the server public key was getting removed
