Fixed a bit of the OnionRequest error handling to better send through server error messages for debugging
Fixed a bug where the initial offset could be negative if the number of messages was less than the page size resulting in a crash
Fixed a crash due to a code path which was thought to be impossible exiting but is actually possible (so just erroring)
Added the 'expire' SnodeAPI endpoint
Removed the 'openGroupServerTimestamp' property (was unused and just added confusion)
Updated the logic to always handle the 'fileId' for uploads/downloads as a string instead of casting it to an Int64
Updated the OpenGroup room parsing to support either Int or String values for image ids
Fixed some broken file paths
Fixed a couple of bugs with closed groups
Fixed a few migration issues
Fixed a bug with the ProfilePictureView in open groups (was including the open parenthesis in the initials)
Migrated the Id Blinding changes to work with GRDB
Migrated the call logic to work with GRDB
Updated the code to work the with hard fork changes
Updated the direct file upload/download to use the non-base64 approaches as well
Updated the attachment 'serverId' value to be a string instead of a UInt64 (future-proofing)
Updated the OnionRequest V4 response handling to avoid converting the "response body" part to a string and processing that, instead just slice the byte array (ie. stopped it from being broken from multiple conversions)
Removed the base64-based file upload/download endpoints (no use including them when they are inefficient and we don't want to use them)
Got the updated file upload working
Removed the legacy 'room' header
Consolidated a number of types between SOGS, FileServer and general requests
Updated the OnionRequestAPI to deal with a Data payload (rather than encoding it to a string and then back to data)
