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
Added unit tests for the MessageReceiver+Decryption extension functions
Updated the unit test key constants to be consistent with the SOGS auth-example keys for consistency
Pointing Curve25519 to use a fork that exposes an XEd25519 conversion method
Fixed an issue where I had broken all message sending due to the SnodeAPI casting Onion responses to `Any`
Added a few types to make the code more readable
Added the inbox request to the polling
Added a couple of properties to the TSContactThread to indicate the originating open group to support SOGS DMs
Added code to store the latest message id for an open group inbox
Added a bunch of documentation from the API docs into the OpenGroupAPI (and associated models)
Updated the OpenGroupAPI to match the latest docs
Fixed the incorrect structure of the SendDirectMessageRequest
Fixed an incorrect inbox endpoint path
Tweaked the batch response handling so it wouldn't fail to parse all responses if a single one failed
Renamed IdPrefix to SessionId.Prefix and cleaned up the type to be more readable & self-documenting
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
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
