Gif background functionality (#29)

* Merge dev and master btanches (#28)

* Update host URL in ResourceKeysDictionary

The host URL used in the ResourceKeysDictionary file has been updated from a local address to a production address. Additionally, a minor formatting change was made in the OverviewPageViewModel file.

* Replace submodule update with git clone in scripts

The git submodule update command in both the 'load-repositories.sh' and 'load-repositories.bat' scripts has been replaced with git clone. This allows for repositories 'GamerVII.Notification.Avalonia' and 'Gml.Client' to be cloned directly instead of being updated through submodules.

* Update system service, resources, and application UI

The system service has been updated to asynchronously load system data. Additional resource keys and corresponding translations have been added to the localization service. Several changes have been made to the application user interface including a new splash screen, application icon, and version number.

* Update submodule link Gml.Client

* Add error tracking to AsyncStreamToImageLoader

The update wraps the core logic of the OnSourceChanged method inside a try-catch block. In case of any exceptions during execution, they are captured and sent to Sentry for error tracking and troubleshooting. This ensures smoother runtime and easier debugging.

* Update host URL and clean up code

The host URL in the ResourceKeysDictionary file was changed from a local IP address to an external URL "https://gmlb.recloud.tech".

* Add GIF decoding functionality

Introduced several new classes to handle the decoding of GIF files. This includes reading the data stream and processing headers, frames, color tables, and extensions. Functionality for rendering frames and handling exceptions has also been implemented.

* Refactor code and optimize exceptions in gif decoder

Code for gif decoding has been refactored for improved readability and efficiency. The exception handling has been optimized for specific errors, such as LzwDecompressionException, contributing to better error reporting and debugging. Unnecessary comments and code have also been removed.

* Remove unnecessary whitespace in AsyncStreamToImageLoader

This commit eliminates a redundant line in the AsyncStreamToImageLoader class file. The change helps to maintain the cleanliness and readability of the code.
