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
Fixed some compilation issues.
Removed an unused dependency.
Cleaned up the Podfile to minimise duplication.
Pointed at an oxen fork of SignalCoreKit instead of a personal one.
Added code to indicate the app won't load LinkPreviews for HTTP urls.
Updated the title & subtitle layout to better handle LinkPreview errors.
Missed an Objective C change in the last commit.
Included the Podfile changes for building on an M1 Mac (Need to shift from personal to session fork).
Fixed some additional build issues due to unwrapping a non-optional type (Swift version?).
