• Updated to GRDB 7.3.0 (from 6.29.3)
• Updated the ConfigMessageReceiveJob and MessageReceiveJob to use the `writeAsync` function (instead of the blocking `write` function) so that they aren't subject to the `Storage.transactionDeadlockTimeoutSeconds`
• Refactored the `Storage.performOperation` and `Storage.performPublisherOperation` to rely on the new cancellable async/await `Task` logic that GRDB 7 supports (as apparently the other async methods don't support cancellation...)
• Cleaned up some "Sendable" related warnings
• Minor tweaks to `Log.assertOnMainThread` to make it a little more readable
• Using a pre-built version of libSession as a SPM dependency for default builds
• Added a new scheme which will try to build libSession from source (update the `LIB_SESSION_SOURCE_DIR` User-Defined build setting to change the location - currently set to '${SRC_ROOT}/../LibSession-Util')
• Removed the libSession submodule
• Refactored the remaining `SNLog` calls
• Added support for a 'customSuffix' to the log categories (similar to the 'customPrefix' it allows category name manipulation whilst keeping the existing log level settings)
• Improved logging in the PN extension
• Fixed an issue where the PN extension would end up with duplicate logs every time a new PN was received
• Fixed an issue where the PN extension would needlessly dispatch it's setup to the main thread
• Fixed an issue where the PN extension would try to read from the database after suspending it
• Fixed an issue where the PN extension could try to complete on a non-main thread (eg. db threads) which _might_ cause odd behaviours
• Tweaked some background poller logs
• Refactored the `BackgroundFetch` handling to use a `DispatchSourceTimer` instead of `NSTimer` and use a specific `DispatchQueue` to avoid race conditions
• Refactored the BackgroundTaskManager to use `DispatchQueue` and `DispatchSourceTimer` and removed unused code (was seeing background tasks incorrectly running too long so wanted to clean it up)
• Fixed an issue where pollers would incorrectly be released during background polling
• Fixed an issue where the background poller wouldn't update the app notification badge count
• Fixed an issue where the community pollers 'timeSinceLastPoll' was incorrectly being given both an epoch timestamp as well as a duration since the last poll (resulting in always just refetching recent messages)
• Fixed an issue where the community poller wasn't updating the last poll timestamp (also renamed some functions to make them clearer)
• Fixed an issue where pollers could incorrectly be started in the background (eg. when receiving a PN)
