feat: Update app.py to use new Tile-Upscaler client

The code changes in app.py update the `upscale` function to use a new client called `other_client` from the `gokaygokay/Tile-Upscaler` repository. This change replaces the commented out code that was using the previous client. The `upscale` function now calls the `predict` method of the `other_client` to perform image upscaling with the provided parameters.
